Subject: Input: alps - fix v4 button press recognition
From: Andreas Bosch <linux@xxxxxxxxxxx>
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")
