Subject: [PATCH 5/9] video: stm: read interface width from device tree
Date: Mon,  6 Jul 2015 12:36:10 +0200	[thread overview]
Message-ID: <1436178974-20064-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1436178974-20064-1-git-send-email-s.hauer@pengutronix.de>

The interface width has not been initialized when probed from device
tree. Fix that.
