Subject: fs: btrfs: simplify close_ctree_fs_info()
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=3b00a6bafc726a9a9df45346fb734d9ecef7b428;p=u-boot.git

fs: btrfs: simplify close_ctree_fs_info()

At the beginning of close_ctree_fs_info() the value 0 is assigned to err
and never changed before testing it.

Let's get rid of the superfluous variable.

Fixes: f06bfcf54d0e ("fs: btrfs: Crossport open_ctree_fs_info() from btrfs-progs")
