Subject: [PATCH 5/8] mtd: Only call of_parse_partitions when the mtd has a parent
Date: Thu, 13 Feb 2014 11:25:32 +0100 [thread overview]
Message-ID: <1392287135-445-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1392287135-445-1-git-send-email-s.hauer@pengutronix.de>
mtd->parent is optional so we can't derefence mtd->parent->device_node
without checking mtd->parent.
