Subject: [media] mt9v032: fix hblank calculation
Author:  Philipp Zabel <p.zabel@xxxxxxxxxxxxxx>
Date:    Mon May 26 10:55:51 2014 -0300

Since (min_row_time - crop->width) can be negative, we have to do a signed
comparison here. Otherwise max_t casts the negative value to unsigned int
and sets min_hblank to that invalid value.
