platform/x86: asus-wmi: Map 0x2a code, Ignore 0x2b and 0x2c events
Browse files Browse the repository at this point in the history
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.
