Subject: [PATCH] HID: input: add mapping for "Toggle Display" key
Git-commit: c01908a14bf735b871170092807c618bb9dae654
Patch-mainline: v5.1-rc6
References: bsc#1051510
According to HUT 1.12 usage 0xb5 from the generic desktop page is reserved
for switching between external and internal display, so let's add the
mapping.
