HID: Add mapping for Microsoft Win8 Wireless Radio Controls extensions (61df56be) · Commits · 戴 / test

Microsoft has defined some extra HUT codes for the Generic Desktop Page for Wireless Radio controls, see: https://docs.microsoft.com/en-us/windows-hardware/drivers/hid/airplane-mode-radio-management https://web.archive.org/web/20170509144631/https://docs.microsoft.com/en-us/windows-hardware/drivers/hid/airplane-mode-radio-management I've 3 2-in-1 keyboard docks: Dell Venue Pro 11 keyboard dock, HP pavilion x2 keyboard dock and a PEAQ C1010 keyboard dock which have a wireless radio toggle hotkey, which uses the 0x000100c6 HUT code defined in these extensions. This commit adds a mapping for this key, this makes the rfkill toggle hotkey work on the Dell Venue Pro 11 and HP Pavilion X2 keyboards, the PEAQ C1010 keyboard does generate events for the 0x000100c6 HUT code when pressed, but the reported value is always 0.
