3.8.13.16 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Jonathan Cameron <jic23@kernel.org>
commit e39d99059ad7f75d7ae2d3c59055d3c476cdb0d9 upstream.
Note this also sets the endianness to big endian whereas it would previously have defaulted to the cpu endian. Hence technically this is a bug fix on LE platforms.
