Subject: [PATCH 20/27] drivers/watchdog: don't check resource with devm_ioremap_resource
Date: Tue, 23 Jul 2013 20:01:53 +0200	[thread overview]
Message-ID: <1374602524-3398-21-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1374602524-3398-1-git-send-email-wsa@the-dreams.de>

devm_ioremap_resource does sanity checks on the given resource. No need to
duplicate this in the driver.
