Subject: [PATCH 08/33] drivers/i2c/busses: don't check resource with devm_ioremap_resource
Date: Thu, 16 May 2013 13:15:36 +0200 [thread overview]
Message-ID: <1368702961-4325-9-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1368702961-4325-1-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.
