[PATCH 2/3] platform/x86: dell-wmi: add new keymap type 0x0012

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Ignore events with a type of 0x0012 and a code of 0xe035,
this silences the following messages being logged when
pressing the Fn-lock key on a Dell Inspiron 5593:

dell_wmi: Unknown WMI event type 0x12
dell_wmi: Unknown key with type 0x0012 and code 0xe035 pressed
