Subject: [PATCH] platform/x86: hp-wmi: Ignore Win-Lock key events

Follow up from https://lore.kernel.org/all/20230120221214.24426-1-rishitbansal0@gmail.com/

There is a "Win-Lock" key on HP Omen Laptops which supports
enabling and disabling the Windows key, which trigger commands 0x21a4
and 0x121a4 respectively. Currently the hp-wmi driver throws warnings
for this event. These can be ignored using KE_IGNORE as the
functionality is handled by the keyboard firmware itself.
