Subject: mm/mmap.c: remove redundant statement "error = -ENOMEM"
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e6ee219fdd69c87ceaeb421bcd753a63937f8f31;p=openwrt%2Fstaging%2Fblogic.git

mm/mmap.c: remove redundant statement "error = -ENOMEM"

It is still a little better to remove it, although it should be skipped
by "-O2".
