Subject: [PATCH AUTOSEL 5.12 02/49] HID: asus: Filter keyboard EC for old ROG keyboard

From: Luke D Jones <luke@...nes.dev>

[ Upstream commit 4bfb2c72b2bfca8684c2f5c25a3119bad016a9d3 ]

Older ROG keyboards emit a similar stream of bytes to the new
N-Key keyboards and require filtering to prevent a lot of
unmapped key warnings showing. As all the ROG keyboards use
QUIRK_USE_KBD_BACKLIGHT this is now used to branch to filtering
in asus_raw_event.
