Subject: [PATCH] platform/x86: asus-wmi: Map 0x2a code, Ignore 0x2b and 0x2c events
Git-commit: 235985d1763f7aba92c1c64e5f5aaec26c2c9b18
Patch-mainline: v6.6-rc7
References: git-fixes

Newer Asus laptops send the following new WMI event codes when some
of the F1 - F12 "media" hotkeys are pressed:

0x2a Screen Capture
0x2b PrintScreen
0x2c CapsLock

Map 0x2a to KEY_SELECTIVE_SCREENSHOT mirroring how similar hotkeys
are mapped on other laptops.

PrintScreem and CapsLock are also reported as normal PS/2 keyboard events,
map these event codes to KE_IGNORE to avoid "Unknown key code 0x%x\n" log
messages.
