X-Git-Url: http://git.archive.openwrt.org/?p=project%2Ffstools.git;a=commitdiff_plain;h=efacbcb4973161c12cc9630d243669845db41a17;ds=inline

ubi: fix false positive in volume_find

An off-by-one made the string compare check only the string
length and not the terminating \0 which lead to rootfs being
found as rootfs_data.
