Hi Dmitry,

Tested the series on a ThinkPad T490, v7.2.3 with CONFIG_PROVE_LOCKING. The
patched and unpatched modules behaved identically and there were no lockdep
reports. debug_locks stayed 1 throughout.

Tested the hotkey, NVRAM polling, DYTC profile, keyboard backlight, fan
control, error paths, module reload and suspend/resume paths.

Thanks,
Ali
