[PATCH] staging: drivers: hid: hid-asus.c: Optimized input logic for keys
From: Johan Boger
Date: Mon May 09 2022 - 06:14:09 EST
Instead of calling asus_map_key_clear() function in each case,
we now set a temporary value and clear it after default.
Patch was checked by checkpatch and adjusted accordingly.
