Subject: [PATCH] ubi: add setting devnum to ubiattach
Date: Thu, 28 Aug 2014 13:01:41 +0200	[thread overview]
Message-ID: <1409223701-1124-1-git-send-email-m.grzeschik@pengutronix.de> (raw)

Sometimes we need to have a defined devicenumber for the ubi partitions.
This patch adds the option to ubiattach.
