Subject: btrfs: remove a useless return statement in btrfs_block_rsv_add
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5a2cb25ab9da5046f10e773c9ecfdb3339f3dd7c;p=linux.git

btrfs: remove a useless return statement in btrfs_block_rsv_add

Since ret must be 0 here, don't have to return.  No functional change
and code readability is not hurt.
