3.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andreas Bosch <[email protected]>

commit b0cfb794a3dd1d699f3e453f9180bd06508fb8f0 upstream.

Since the change to struct input_mt_pos some variables are now bitfields
instead of integers. Automatic conversion from integer to bitfield entry
destroys information, therefore enforce boolean interpretation instead.

Fixes: 02d04254a5df ("Input: alps - use struct input_mt_pos to track 
coordinates")
