True, although I'd be very surprised if anything else came up :)

Yes, the rationale behind the name really isn't obvious but all meanings 
are sorta correct, so it's not that bad :P

I like tpkbd_drvdata better though, and can correct it in the compact 
keyboard code too. I wanted to make the variable names match, but didn't 
get around to it, so will do it next time around.

The key other place I can think of that this happens is for the USB 
compact keyboard, for it's HID_TYPE_USBMOUSE half (versus the keyboard 
half). Saying trackpoint there is a mis-truth, since it's also where all 
the extra keys hide. But I'll have a look through anyway.
