| Subject: HID: input: add mapping for "Toggle Display" key |
| |
| [ Upstream commit c01908a14bf735b871170092807c618bb9dae654 ] |
| |
| 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. |
