This patchset follows on from my previous attempts to add support for
these keyboards from Lenovo.

Antonio, I've used cptkbd_data and left data_pointer for now. It'd be
an easy patch to change data_pointer to tpkbd_data, but is drifting
away from what this patchset is supposed to do. Could send that
afterwards though.

Sure, no problem. I think we are good to go.

BTW I was considering picking up one of such compact keyboards myself,
but I read that the BT one uses the USB cable only for charging
and it does not show as a USB HID device when plugged in, can you
confirm that?

Yes, nothing happens over USB other than charging. It's slightly 
irritating since I have to keep something else to hand for booting, or try 
and get a dongle that goes into a HID proxy mode.

That said, I quite like it as a keyboard and happily use it for working 
all day. Interestingly the bluetooth version is nicer to type on than the 
USB version, even though they look physically identical. This could be 
they came from different batches rather than using better keys for the 
Bluetooth version.

Thanks,
  Antonio
