Re: [PATCH] [MTD-UTILS] Incorrect loop condition

[Jehan Bing <jehan@orb.com>]

Small patch to fix an obvious typo.

If the file contains only a few bytes in the last page and the --oob option is selected, the loop may exit early (readlen < meminfo.oobsize).
Most of the time it will still work though because the code tries to read the whole OOB in one chunk.
