Subject: mtd: nand: ecc-bch: Return only valid error codes
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e3010bd3ef1eda13f08155fe43846a64d0990a86;p=linux.git

mtd: nand: ecc-bch: Return only valid error codes

When a function is not available, returning -ENOTSUPP makes much more
sense than returning -1.
