Subject: [PATCH 4/7] imx-bbu-nand-fcb: don't drop error return code
Date: Wed,  6 Jul 2016 20:44:37 +0200	[thread overview]
Message-ID: <1467830680-5909-4-git-send-email-dev@lynxeye.de> (raw)
In-Reply-To: <1467830680-5909-1-git-send-email-dev@lynxeye.de>

bit_to_flip might be negative if any uncorrectable bitflips
occured. Use int instead of unsigned type in order to properly
propagate the error.
