Subject: [PATCH 01/15] driver: add dev_get_drvdata function
Date: Wed, 12 Sep 2012 22:06:33 +0200 [thread overview]
Message-ID: <1347480407-16865-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1347480407-16865-1-git-send-email-s.hauer@pengutronix.de>
Drivers need to get their driver data either from devicetree or the platform
information. It should matter for the driver where this data comes from, so
introduce a common function for it.
