linux-stable.git/drivers/platform, branch v7.0.9 Linux kernel stable tree platform/x86: hp-wmi: Ignore backlight and FnLock events 2026-05-17T15:16:25+00:00 Krishna Chomal krishna.chomal108@gmail.com 2026-04-03T08:01:55+00:00 9322368edb55393ac94be838347f69a41ac87c72 commit e8c597368b8500a824c639bfb5ed0044068c6870 upstream. On HP OmniBook 7 the keyboard backlight and FnLock keys are handled directly by the firmware. However, they still trigger WMI events which results in "Unknown key code" warnings in dmesg. Add these key codes to the keymap with KE_IGNORE to silence the warnings since no software action is needed. Tested-by: Artem S. Tashkinov <aros@gmx.com> Reported-by: Artem S.

commit e8c597368b8500a824c639bfb5ed0044068c6870 upstream.

On HP OmniBook 7 the keyboard backlight and FnLock keys are handled
directly by the firmware. However, they still trigger WMI events which
results in "Unknown key code" warnings in dmesg.

Add these key codes to the keymap with KE_IGNORE to silence the warnings
since no software action is needed.

This leads to a NULL dereference when the mutex is later acquired (e.g. in cros_typec_altmode_work()). Initialize the mutex in cros_typec_register_thunderbolt() to fix the issue.
