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.

Nitpicking, but you should probably use HID_GD_WIRELESS_RADIO_CTLS
instead of the constant.
Yeah that is actually why I defined it in the first place, my bad.

Better linking the HUT directly:
http://www.usb.org/developers/hidpage/HUTRR40RadioHIDUsagesFinal.pdf
We probably just need the full link in the commit message, and here only
a reference to HUTRR40.
Ah I did not know about that version, I added the web.archive.org version
because using URLs usually is a bad idea because they tend to go stale.
I will do as you suggested and send a v2 tomorrow.

In the HID usage table extension, they are called "Wireless Radio *".
I wonder if we should have a closer name.
Then we would end up with HID_GD_WIRELESS_RADIO_* ?
Which is a bit long, RFKILL is linux-speak for this,
and nice and short, but if you prefer the long version
let me know and I'll change it for v2.

Hans
