Subject: fs: btrfs: initialize @ret to 0 to prevent uninitialized return value
X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=4891c4e595b48ee41b7d8062bb599d05a938ea0a;p=u-boot.git

fs: btrfs: initialize @ret to 0 to prevent uninitialized return value

In show_dir() if we hit a ROOT_ITEM, we can exit with uninitialized
@ret.

Fix it by initializing it to 0.
