Hi Dmitry,

I've updated the patch with your comments, unregistering first before
freeing the gpios.

In regards of your comment for the gpio-keys-polled update, I've just
started with kernel dev and thought moving old drivers to the new
managed api was a good start.
So I don't really know how to start that. However I'm willing to look
at it if you could give some pointers where to start/how to tacle this.

Regards
Bram
