watchdog: dw_wdt: convert to SIMPLE_DEV_PM_OPS
From: Heiko Stuebner <heiko@...> Date: Wed, 26 Jun 2013 15:05:53 +0200
Commit-Message
The dw_wdt only provides PM_SLEEP operations, so convert the driver to use SIMPLE_DEV_PM_OPS instead of populating the struct manually. This has the added effect of simplifying the CONFIG_PM ifdefs. Signed-off-by: Heiko Stuebner <heiko@...>
