Subject: [129/272] ext4: fix uninitialized variable in ext4_register_li_request

2.6.37-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Andrew Morton <akpm@...ux-foundation.org>

commit 6c5a6cb998854f3c579ecb2bc1423d302bcb1b76 upstream.

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.
