platform/wmi: Replace .no_notify_data with .min_event_size
WMI drivers using the buffer-based WMI API are expected to reject
undersized event payloads. Extend the WMI driver core to allow
such drivers to specify their minimum supported event payload size.
Also remove the now redundant .no_notify_data field.

platform/x86: uniwill-laptop: Fix signedness bug
The function sysfs_match_string() can return negative error codes and
the variable assigned to it is the enum 'option'. Which could be an
unsigned int due to different compiler implementations.

Assign signed variable 'ret' to sysfs_match_string(), check for error,
then assign ret to option.

Detected by Smatch:
drivers/platform/x86/uniwill/uniwill-acpi.c:919 usb_c_power_priority_store()
warn: unsigned 'option' is never less than zero.

platform/x86: uniwill-laptop: Apply features across all TUXEDO devices
Uses the more fine granular and/or new feature defines to enable more

platform/x86: uniwill-laptop: Fix crash on unexpected battery event
On devices that have not UNIWILL_FEATURE_BATTERY set, the underlying
hardware might still send the UNIWILL_OSD_BATTERY_ALERT event. In such
a situation, the driver will access uninitialized data structures when
handling said event.

Prevent this by only handling the UNIWILL_OSD_BATTERY_ALERT event when
UNIWILL_FEATURE_BATTERY is set.

platform/x86: uniwill-laptop: Rename FN lock and super key lock attrs
It turns out that both sysfs attributes actually directly control
the FN lock status/super key enable status, rather than the
triggering of the associated events. This behavior was first observed
on a Tuxedo notebook and was belived to be a hardware quirk.
However, it seems that i simply misunderstood the manual of the
OEM software for Intel NUC devices. The correct behavior is:

- fn_lock_toggle_enable enables/disables FN lock mode
- super_key_toggle_enable enables/disables the super key

Rename both sysfs attributes to avoid confusing users.

bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

platform/x86/uniwill: Implement cTGP setting
Uniwill offers user setable cTGP for their EC on devices using NVIDIA 3000
Series and newer GPUs. This patch implements this setting as a sysfs
attribute.

For one device, the TUXEDO InfinityBook Gen7, the variant with and without
NVIDIA GPU can't be differentiated using only the DMI strings, so the new
probe callback needs to be used to test a bit from the EC memory.

platform/x86/uniwill: Handle more WMI events required for TUXEDO devices
Handle more WMI events that are triggered on TUXEDO devices.

Testing the TUXEDO InfinityBook Pro 15 Gen9 Intel, the Stellaris 16 Gen5
Intel, the Stellaris 16 Gen5 AMD and going through the out of tree
tuxedo-drivers dkms package I identified more WMI events that are used by
Uniwill.

This patch binds them to their respective function, or marks them as
KE_IGNORE when they are send in addition to other actions, to make clear
that they don't need special handling. This also avoids warnings in dmesg.

The events with descriptions from memory:

UNIWILL_OSD_RADIOON and UNIWILL_OSD_RADIOOFF - Sent in addition to the
already handled UNIWILL_OSD_RFKILL on some devices.

UNIWILL_OSD_PERFORMANCE_MODE_TOGGLE - Physical button on some devices. Bind
it to a button so userspace can receive the keypress and do stuff with it.

UNIWILL_OSD_MUTE - Sent in addition to an already handled keypress.

UNIWILL_OSD_KB_LED_LEVEL0 - UNIWILL_OSD_KB_LED_LEVEL4 - Some devices sent
these instead of UNIWILL_OSD_KBDILLUMTOGGLE.

UNIWILL_OSD_WEBCAM_TOGGLE - Sent in addition to deactivating the Webcam on
firmware level.

UNIWILL_OSD_DC_ADAPTER_CHANGED - No special handling required here atm, but
will be for the charging priority feature.

platform/x86: Add Uniwill laptop driver
Add a new driver for Uniwill laptops. The driver uses a ACPI
interface to talk with the embedded controller, but relies on a
ACPI WMI interface for receiving event notifications.

The driver is reverse-engineered based on the following information:
- OEM software from intel
- https://github.com/pobrn/qc71_laptop
- https://gitlab.com/tuxedocomputers/development/packages/tuxedo-drivers
- https://github.com/tuxedocomputers/tuxedo-control-center

The underlying EC supports various features, including hwmon sensors,
battery charge limiting, a RGB lightbar and keyboard-related controls.
