Subject: [PATCH 05/10] mtd nand omap: fail on bch decode failure
Date: Tue, 8 Nov 2011 14:01:48 +0100 [thread overview]
Message-ID: <1320757313-12568-6-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1320757313-12568-1-git-send-email-s.hauer@pengutronix.de>
The driver used to print an error when bch decoing failed, but
did not actually throw an error. Fix this.
