Subject: [PATCH 3.12 023/170] watchdog: sp805: Set watchdog_device->timeout from ->set_timeout()

From: Viresh Kumar <viresh.kumar@...aro.org>

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

===============

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.
