Subject: mtd: tests: ignore corrected bitflips in OOB on mtd_readtest
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=003bc47922047e21ebfb19cb99317273b313f79d;p=mv-sheeva.git

mtd: tests: ignore corrected bitflips in OOB on mtd_readtest

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