Subject: [024/103] V4L/DVB: gspca - sn9c20x: Bad transfer size of Bayer images

2.6.35-stable review patch.  If anyone has any objections, please let us know.

From: Jean-François Moine <moinejf@...e.fr>

commit 04d174e99a6eca2f62b56c10ae1d7d0499d83e9d upstream.

As the end of frame marker does not contain any pixel, it must not be
transferred.
