Also note that in addition to what Jiri said, this is kABI now. People
can change this settings from user-space by adding it into a new_id.
So you should probably add a comment here:
/* 0x0010 reserved, was: APPLE_ISO_KEYBOARD */
This will prevent future submissions to fill the gap and have users
having custom configurations that suddenly break.

Just nitpicking here. I'd prefer see the value 13 in a #define. Just
because it'll be easier to re-read this later.
