Subject: [PATCH 2/3] mtd: tests: ignore corrected bitflips in OOB on mtd_readtest
Date: Tue, 28 Jun 2011 16:28:59 -0700	[thread overview]
Message-ID: <1309303740-9936-3-git-send-email-computersforpeace@gmail.com> (raw)
In-Reply-To: <1309303740-9936-1-git-send-email-computersforpeace@gmail.com>

read_oob may now return ECC error codes. If the code is -EUCLEAN, then
we can safely ignore the error as a corrected bitflip.
