[PATCH v4 16/18] staging: media: zoran: fix TRY_FMT handling

[Corentin Labbe]

From: Hans Verkuil <hans.verkuil@xxxxxxxxx>

TRY_FMT must not set actual capture values (zr->buffer_size in
this case), since it is a 'try' only.

zoran_try_fmt_vid_cap() also didn't fill in fmt->fmt.pix.bytesperline
and fmt->fmt.pix.sizeimage correctly.
