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

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

From: Marc Kleine-Budde <mkl@pengutronix.de>

commit e358784297992b012e8071764d996191dd2b1a54 upstream.

The current implemetation of of_match_device() relies that the of_device_id
table in the driver is sorted from most specific to least specific compatible.

Without this patch the mx28 is detected as the less specific p1010. This leads
to a p1010 specific workaround is activated on the mx28, which is not needed.
