Patch looks good to me, easier to validate now :)

A few ideas below for some possible _future_ cleanups, but no reason to
hold this one any longer IMHO.

Ciao,

This could become:

	Say Y if you want support for the non-HID-compliant features of Lenovo
	devices, e.g:
	...

because, in principle, the driver is not only about keyboards anymore.

I think the word "pointer" here is misleading, sometimes in other parts
of the driver it is used as a synonym of trackpoint, but
lenovo_drvdata_tpkbd also contains data about leds, so here it looks
like it refers to C pointers. I'd call the variable tpkbd_data or
tpkbd_drvdata, throughout the driver. What do you think?

And the driver could standardize on the word "trackpoint" where
appropriate in order to eliminate any ambiguity.

I know, these are not your faults :)
