[PATCH 3/3] platform/x86: dell-wmi: add keys to bios_to_linux_keycode

2020-06-08T04:22:52Z

Increase length of bios_to_linux_keycode to 2 bytes to allow for a new
keycode 0xffff, this silences the following messages being logged at
startup on a Dell Inspiron 5593

dell_wmi: firmware scancode 0x48 maps to unrecognized keycode 0xffff
dell_wmi: firmware scancode 0x50 maps to unrecognized keycode 0xffff
