The device does not really support pressure reading, please don't try
to provide fake reports. Signal touch with BTN_TOUCH.

You should free IRQ first, otherwise IRQ may fire just was device is
unregistered and bad things may happed.
Also please run checkpatch on the driver since there are some
formatting and whitespace issues (note that I dont particularly care
about 80 column limit as long as code is readable).
Thank you.
