Subject: [PATCH 07/14] cdev: Collect partitions on list
Date: Fri, 31 Mar 2017 07:33:16 +0200	[thread overview]
Message-ID: <20170331053323.17821-8-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20170331053323.17821-1-s.hauer@pengutronix.de>

We currently do not have a way to iterate over all partitions of
a cdev. Change this.
