2.6.33-stable review patch. If anyone has any objections, please let me know.

-----------------

From: Baruch Siach <baruch(a)tkos.co.il>

commit 84f3751d6a6f766780dee509433bf7b3dfcdf465 upstream.

When code <= V4L2_MBUS_FMT_FIXED soc_mbus_get_fmtdesc returns a pointer to
mbus_fmt[x], where x < 0. Fix this.
