3.8.13.27 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Viresh Kumar <viresh.kumar@xxxxxxxxxx>
commit 938626d96a3ffb9eb54552bb0d3a4f2b30ffdeb0 upstream.
Implementation of ->set_timeout() is supposed to set 'timeout' field of 'struct
watchdog_device' passed to it. sp805 was rather setting this in a local
variable. Fix it.
