Subject: Btrfs: cleanup: remove unnecessary check before btrfs_free_path is called
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=527afb4493c2892ce89fb74648e72a30b68ba120;p=linux-beck.git

Btrfs: cleanup: remove unnecessary check before btrfs_free_path is called

We need not check path before btrfs_free_path() is called because
path is checked in btrfs_free_path().
