Subject: [media] ov7670: fix QVGA visible area
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dc4589c814a3a50a4cfc2077690fc7fd397308c8;p=linux-beck.git

[media] ov7670: fix QVGA visible area

The QVGA mode has a green horizontal line on the left hand side, and a red
(or sometimes blue) vertical line at the bottom. Tweak the visible area
to remove them.

Thanks to Mauro for explaining how to fix this.
