Hi all,
I would like to request a backport of commit e8c597368b85 [1] to Linux
7.0.y, and LTS versions.
On new HP OmniBook 7 (Panther Lake) hardware, the keyboard backlight
and FnLock keys are handled by firmware but still trigger WMI events.
This results in "Unknown key code" warnings spamming dmesg [2].
The mainline commit e8c597368b85 ("platform/x86: hp-wmi: Ignore backlight
and FnLock events") silences these warnings by adding the key codes to
the keymap with KE_IGNORE.
The patch was merged in v7.1-rc1 but missed the stable tag during
initial submission.
Thanks
