[Greg KH]

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

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

From: Jean-Francois Moine <moinejf@xxxxxxx>

commit 07d1c69b2dcfdd1b21e36af0ff8b9506234908ee upstream.

A previous code optimization inverted bridge registers and values,
doing a regression in kernel  2.6.32.
