Subject: ext4: fix uninitialized variable in ext4_register_li_request
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6c5a6cb998854f3c579ecb2bc1423d302bcb1b76;p=openwrt%2Fstaging%2Fblogic.git

ext4: fix uninitialized variable in ext4_register_li_request

fs/ext4/super.c: In function 'ext4_register_li_request':
fs/ext4/super.c:2936: warning: 'ret' may be used uninitialized in this function

It looks buggy to me, too.
