platform/x86: asus-armoury: fix mini-LED mode get/set on MODE2 devices
The mini-LED current_value attribute does not work on devices that use
ASUS_WMI_DEVID_MINI_LED_MODE2 (2024 and newer models).

Reading is broken: mini_led_mode_current_value_show() fetches the mode
from the device but then decodes a literal 0 instead of the value it
just read:

    mode = FIELD_GET(ASUS_MINI_LED_MODE_MASK, 0);

So mode is always 0, and the attribute always reports the same thing
regardless of the real hardware state.

Writing is broken too. The number a user writes is an index; the value
the firmware actually wants is looked up from that index in
mini_led_mode_map[]. mini_led_mode_current_value_store() skips that
lookup and passes the raw index straight to armoury_attr_uint_store().
On 2024 devices the firmware numbers its modes differently from the
index, so some writes are rejected with -EINVAL and the rest send the
wrong mode to the hardware.

Fix both paths: decode the value actually read from the device when
reading, and look up the firmware value before sending it when
writing. Older (MODE1) devices were unaffected because there the index
and the firmware value are the same.

platform/x86/intel/vsec: Fix enable_cnt imbalance on PCIe error recovery
After a PCIe Uncorrectable Error has been reported by a device with
Intel Vendor Specific Extended Capabilities and has been recovered
through a Secondary Bus Reset, its driver calls intel_vsec_pci_probe()
to rescan and reinitialize VSECs.

intel_vsec_pci_probe() invokes pcim_enable_device() and thereby adds
another devm action which calls pcim_disable_device() on driver unbind.

So once the driver unbinds, pcim_disable_device() will be called as many
times as an Uncorrectable Error occurred, plus one.  This will lead to
an enable_cnt imbalance on driver unbind.

Additionally, since commit dc957ab6aa ("platform/x86/intel/vsec: Add
private data for per-device data"), a devm_kzalloc() allocation is
leaked on every Uncorrectable Error.

Avoid by splitting the VSEC rescan out of intel_vsec_pci_probe() into a
separate helper and calling that on PCIe error recovery.

platform/x86: uniwill-laptop: Do not enable the charging limit even when forced

platform/x86: uniwill-laptop: Accept charging threshold of 0
The power supply sysfs ABI states that:

	Not all hardware is capable of setting this to an arbitrary
	percentage. Drivers will round written values to the nearest
	supported value. Reading back the value will show the actual
	threshold set by the driver.

The driver currently violates this ABI by rejecting a charging
threshold of 0. Fix this by clamping this value to 1.

platform/x86: lenovo-wmi-other: Limit adding attributes to supported devices
Adds lwmi_is_attr_01_supported, and only creates the attribute subfolder
if the attribute is supported by the hardware. Due to some poorly
implemented BIOS this is a multi-step sequence of events. This is
because:
- Some BIOS support getting the capability data from custom mode (0xff),
  while others only support it in no-mode (0x00).
- Some BIOS support get/set for the current value from custom mode (0xff),
  while others only support it in no-mode (0x00).
- Some BIOS report capability data for a method that is not fully
  implemented.
- Some BIOS have methods fully implemented, but no complimentary
  capability data.

To ensure we only expose fully implemented methods with corresponding
capability data, we check each outcome before reporting that an
attribute can be supported.

Checking for lwmi_is_attr_01_supported during remove is not done to
ensure that we don't attempt to call cd01 or send WMI events if one of
the interfaces being removed was the cause of the driver unloading.

platform/x86: lenovo-wmi-helpers: Move gamezone enums to wmi-helpers

An additional patch in the series will also add a function prototype that
needs to reference this enum in wmi-helpers.h. To avoid having all these
drivers begin to import each others headers, and to avoid declaring an
opaque enum to hande the second case, move the thermal mode enum to
helpers where it can be safely accessed by everything that needs it from
a single import.

While at it, since the gamezone_events_type enum is the only remaining
item in the header, move that as well and remove the gamezone header
entirely.

platform/x86: lenovo: Decouple lenovo-wmi-gamezone and lenovo-wmi-other
Currently, lenovo-wmi-gamezone depends on lenovo-wmi-other as the former
imports symbols from the latter. The imported symbols are just used to
register a notifier block. However, there is no runtime dependency
between both drivers, and either of them can run without the other,
which is the major purpose of using the notifier framework.

Such a link-time dependency is non-optimal. A previous attempt to "fix"
it made LENOVO_WMI_GAMEZONE select LENOVO_WMI_TUNING, which was
fundamentally broken and resulted in undefined Kconfig behavior, as
`select' cannot be used on a symbol with potentially unmet dependencies.

Decouple both drivers by moving the thermal mode notifier chain to
lenovo-wmi-helpers. Methods for notifier block (un)registration are
exported for lenovo-wmi-gamezone, while a method for querying the
current thermal mode are exported for lenovo-wmi-other.

This turns the dependency graph from

            +------------ lenovo-wmi-gamezone
            |                     |
            v                     |
    lenovo-wmi-helpers            |
            ^                     |
            |                     V
            +------------ lenovo-wmi-other

into

            +------------ lenovo-wmi-gamezone
            |
            v
    lenovo-wmi-helpers
            ^
            |
            +------------ lenovo-wmi-other

To make it clear, the name of the notifier chain is also renamed from
`om_chain_head' to `tm_chain_head', indicating that it's used to query
the current thermal mode.

No functional change intended.

platform/x86: lenovo-wmi-other: Balance component bind and unbind
When lwmi_om_master_bind() fails, the master device's components are
left bound, with the aggregate device destroyed due to the failure
(found by sashiko.dev [1]).

Balance calls to component_bind_all() and component_unbind_all() when an
error is propagated to the component framework.

No functional change intended.

platform/x86: lenovo-wmi-other: Balance IDA id allocation and free
Currently, the IDA id is only freed on wmi-other device removal or
failure to create firmware-attributes device, kset, or attributes. It
leaks IDA ids if the wmi-other device is bound multiple times, as the
unbind callback never frees the previously allocated IDA id.
Additionally, if the wmi-other device has failed to create a
firmware-attributes device before it gets removed, the wmi-device
removal callback double frees the same IDA id.

These bugs were found by sashiko.dev [1].

Fix them by moving ida_free() into lwmi_om_fw_attr_remove() so it is
balanced with ida_alloc() in lwmi_om_fw_attr_add(). With them fixed,
properly set and utilize the validity of priv->ida_id to balance
firmware-attributes registration and removal, without relying on
propagating the registration error to the component framework, which is
more reliable and aligns with the hwmon device registration and removal
sequences.

No functional change intended.

platform/x86/intel/tpmi/plr: Prevent fault during unbind
This driver faults when intel vsec driver is unbound from PCI driver
interface. For example:

echo 0000:00:03.1 > /sys/bus/pci/drivers/intel_vsec/unbind

This is caused by accessing plr->dbgfs_dir after vsec_tpmi driver is
removed. Here vsec_tpmi driver is the parent. On unbind, the parent
device remove callback is called first which here will remove debugfs
interface. Hence plr->dbgfs_dir is no longer valid.

Register notifier for TPMI_CORE_EXIT and make this pointer to NULL,
so that debugfs_remove_recursive() is not called with bad plr->dbgfs_dir
pointer.

After notifier is returned the vsec_tpmi driver will call remove debugfs
by calling debugfs_remove_recursive().

In some cases a driver using services of vsec_tpmi driver requires some

This is the case when unbind using PCI driver interface. In this case
the remove callback of vsec_tpmi driver is called first, then remove
callback of its children.

Add support of blocking chain notifiers support. Notify on successful probe
and before clean up in the remove callback.

platform/x86: samsung-galaxybook: Handle ACPI hotkey notifications
On Samsung Galaxy Book 5 (SAM0430), the keyboard backlight, microphone
mute, and camera block hotkeys do not generate i8042 scancodes.
Instead they arrive as ACPI notifications 0x7d, 0x6e, and 0x6f
respectively, all of which previously fell through to the default
"unknown" warning in galaxybook_acpi_notify().

Add handling for these three events:

 - 0x7d (Fn+F9, keyboard backlight): schedule the existing
   kbd_backlight_hotkey_work which cycles brightness.

 - 0x6e (Fn+F10, microphone mute): emit KEY_MICMUTE via the driver's
   input device.

 - 0x6f (Fn+F11, camera block): if block_recording is active use the
   existing block_recording_hotkey_work; otherwise emit a toggle of
   SW_CAMERA_LENS_COVER via the driver's input device on models where
   the block_recording ACPI feature is not supported.

Tested on Samsung Galaxy Book 5 (SAM0430) and Samsung Galaxy Book2 Pro
(SAM0429).

platform/x86: hp-wmi: silence unknown board warning for 8D41
The HP Omen Max 16-ah0xxx, DMI board ID 8D41 is currently marked with
victus_s_thermal_params in the victus_s_thermal_profile_boards[] list.
This disables thermal profile readback and adds a dmesg warning during
driver init for "unknown board".

After testing we know that (similar to another HP Omen Max 16 device,
board ID 8D87), the embedded controller on this board does not expose
thermal profile which means we have to intentionally disable EC
readback.

Changing its driver_data to omen_v1_no_ec_thermal_params is sufficient
to silence the warning.

25ff5848c0 tools/power x86_energy_perf_policy: Enhances SoC Slider related checks
When processor_thermal_soc_slider is loaded, its slider
and offset modparams are visible.  Check that the driver
actually registered the profile named "SoC Slider" before
reading or writing these modparams.

n.b. This utility allows writing the Slider and Offset modparams
even if the driver policy is not "balanced".  Currently the
processor_thermal_soc_slider consults those modparams
only in "balanced" mode.

clk: bcm: rpi: Mark VEC clock as CLK_IGNORE_UNUSED
On Raspberry Pi 3B, the VEC clock is used by the VideoCore firmware
display driver, which remains active until the vc4 driver loads and
sends NOTIFY_DISPLAY_DONE. If this clock is disabled during boot, a bus
lockup happens and the firmware becomes unresponsive, causing a complete
system lockup.

Mark the VEC clock with CLK_IGNORE_UNUSED so it survives the unused
clock disablement and remains available until the vc4 driver takes over
display management.

27d128c1cf ring-buffer fix for 7.1:
- Fix accounting of persistent ring buffer rewind
 
   On boot up, the head page is moved back to the earliest point of
   the saved ring buffer. This is because the ring buffer being read by
   user space on a crash may not save the part it read. Rewinding the head
   page back to the earliest saved position helps keep those events from
   being lost.
 
   The number of events is also read during boot up and displayed in the
   stats file in the tracefs directory. It's also used for other accounting
   as well. On boot up, the "reader page" is accounted for but a rewind may
   put it back into the buffer and then the reader page may be accounted
   for again.
 
   Save off the original reader page and skip accounting it when scanning
   the pages in the ring buffer.

 - Fix for a NOMMU bug with io_uring, where NOMMU doesn't grab page refs
   at mmap time. NOMMU also has entirely broken FOLL_PIN support, yet
   here we are

 - A few fixes covering minor issues introduced in this merge window

 - data race annotation to shut up KCSAN for when io-wq limits are
   applied

 - A nospec addition for direct descriptor file updating. Rest of the
   direct descriptor path already had this, but for some reason the
   update did not. Now they are all the same

 - Various minor defensive changes that claude identified and suggested
   terrible fixes for, turned into actually useful cleanups:

       - Use kvfree() for the imu cache. These can come from kmalloc or
         vmalloc depending on size, but the in-cache ones are capped
         where it's always kmalloc based. Change to kvfree() in the
         cleanup path, making future changes unlikely to mess that up

       - Negative kbuf consumption lengths. Can't happen right now, but
         cqe->res is used directly, which if other codes changes could
         then be an error value

 - Fix for an issue with the futex code, where partial wakes on a
   vectored fuxes would potentially wake the same futex twice, rather
   than move on to the next one. This could confuse an application as it
   would've expected the next futex to have been woken

 - Fix for a bug with ring resizing, where SQEs or CQEs might not have
   been copied correctly if large SQEs or CQEs are used in the ring.
   Application side issue, where SQEs or CQEs might have been lost
   during resize

 - Fix for a bug where EPOLL_URING_WAKE might have been lost, causing a
   multishot poll to not be terminated when it's nested, like it should
   have been

 - Fix for an issue with signed comparison of poll references for the
   slow path
