Subject: btrfs: remove unnecessary check of iput argument
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8aa1e49ea1fdcc585be4bcfe8c62684a087cc7c6;p=linux.git

btrfs: remove unnecessary check of iput argument

iput() already handles NULL and non-NULL parameter, so it is not needed
to check that. This unifies all iput calls.
