Subject: [MTD] [NAND] make s3c2410 indicate an error for multi-bit read errors
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4fac9f698404a5cd50b978fbdb7e54235353c215;p=openwrt%2Fstaging%2Fblogic.git

[MTD] [NAND] make s3c2410 indicate an error for multi-bit read errors

If there were multiple bit errors in the data s3c2410_nand_correct_data()
was returning 0 (no error) instead of -1, so the upper layers (like JFFS2)
would not know the data is corrupt.
