Subject: [PATCH 4/8] mtd: erase_info may be modified in mtd_erase
Date: Thu, 13 Feb 2014 11:25:31 +0100 [thread overview]
Message-ID: <1392287135-445-4-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1392287135-445-1-git-send-email-s.hauer@pengutronix.de>
erase_info may be modified by the mtd partition code, so
set the address each time we call mtd_erase.
