The Lenovo GameZone/Other interfaces have some delicate divergences
among different devices. When making a bug report or adding support for
new devices/interfaces, capdata is the most important information to
cross-check with.
Add a debugfs file (lenovo_wmi/<device_name>/capdata), so that users can
dump capdata and include it in their reports.
Since `struct capdata01' is just an extension to `struct capdata00',
also convert the former to include the latter anonymously
(-fms-extensions, since v6.19). This is declared as a union in the
capdata01 struct, with both the anonymous declaration and as a named
member to avoid type casting when passing just the capdata00 struct
pointer.

We are about to add debugfs support for lenovo-wmi-capdata. Let's setup
a debugfs directory called "lenovo_wmi" for tidiness, so that any
lenovo-wmi-* device can put its subdirectory under the directory.
Subdirectories will be named after the corresponding WMI devices.

Some Lenovo BIOS have been shown to have incomplete and/or broken
capability data and WMI attribute IDs. In some cases the capability data
reports that a feature is not supported when the get/set methods are
fully implemented. It is also possible that the ACPI methods from the
ideapad_laptop driver we defer to could be bugged while the WMI method
is fully working. To aid end users in submitting more complete bug
reports in these situations, add an override to skip the ACPI and
compatibility checks to force load the power supply extension as if it
is fully supported and has no conflicts.

Add charge_behaviour and charge_types attributes through a power supply
extension for devices that support WMI based charge enable & disable.
Lenovo Legion devices that implement WMI function and capdata ID
0x03010001 in their BIOS are able to enable or disable charging at 80%
through the lenovo-wmi-other interface. Add a charge_types attribute for
BATX devices to expose this capability with Standard and Long_Life types
enabled.
Additionally, devices that support WMI function and capdata ID 0x03020000
are able to force discharge of the battery. Expose this capability with
a charge_behaviour attribute in the power supply extension, with the auto
and force-discharge behaviors enabled. The GET method for this attribute
is bugged. After analyzing the DSDT, and some testing, it appears the
method grabs bit(3) instead of bit(4) from the EC register that stores the
current status, and will only report if charging has been inhibited or
not. To work around this, store and report the last setting written to the
attribute.
As some devices only expose one attribute or the other, a bitmask is
added with a lookup table and some helper macros to select the correct
configuration for the hardware at runtime.
The ideapad_laptop driver provides the charge_types attribute to provide
similar functionality. When the WMI method is set this can corrupt the
ACPI method return and cause hardware and driver errors. To avoid
conflicts between the drivers, we get the acpi_handle and do the same
check that ideapad_laptop does when it enables the feature. If the
feature is supported in ideapad_laptop, abort adding the extension from
lenovo-wmi-other. The ACPI method is more reliable when both are
present from my testing, so we can prefer that implementation and do
not need to worry about de-conflicting from inside that driver.

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.

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.
