Subject: [PATCH] platform/x86: asus-wmi: Ignore WMI events with codes 0x7B, 0xC0
Git-commit: 362c1f2ec82cb65940e1c73e15a395a7a891fc6f
Patch-mainline: v6.4-rc4
References: git-fixes

On ASUS GU604V the key 0x7B is issued when the charger is connected or
disconnected, and key 0xC0 is issued when an external display is
connected or disconnected.

This commit maps them to KE_IGNORE to slience kernel messages about
unknown keys, such as:

    kernel: asus_wmi: Unknown key code 0x7b
