3.8.13.16 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Charles Keepax <[email protected]> commit 939fd1e8d9deff206f12bd9d4e54aa7a4bd0ffd6 upstream. Some devices are getting very close to the limit whilst polling the RAM start, this patch adds a small delay to this loop to give a longer startup timeout.
