Subject: media: mt9v032: fix hblank calculation
From: Philipp Zabel <p.zabel@xxxxxxxxxxxxxx>
commit f17bc3f4707eb87bdb80b895911c551cdd606fbd upstream.
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.
