Subject[PATCH AUTOSEL 6.1 14/20] platform/x86: hp-wmi: Handle Omen Key event
Date
From: Rishit Bansal <rishitbansal0@gmail.com>

[ Upstream commit 3ee5447b2048c8389ed899838a40b40180d50906 ]

Add support to map the "HP Omen Key" to KEY_PROG2. Laptops in the HP
Omen Series open the HP Omen Command Center application on windows. But,
on linux it fails with the following message from the hp-wmi driver:

[ 5143.415714] hp_wmi: Unknown event_id - 29 - 0x21a5

Also adds support to map Fn+Esc to KEY_FN_ESC. This currently throws the
following message on the hp-wmi driver:

[ 6082.143785] hp_wmi: Unknown key code - 0x21a7

There is also a "Win-Lock" key on HP Omen Laptops which supports
Enabling and Disabling the Windows key, which trigger commands 0x21a4
and 0x121a4 respectively, but I wasn't able to find any KEY in input.h
to map this to.
