Subject: btrfs: Remove BUG_ON from __finish_chunk_alloc()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3acd395317f22b4346a139571cd4723408c5d4af;p=mv-sheeva.git

btrfs: Remove BUG_ON from __finish_chunk_alloc()

btrfs_alloc_chunk() unconditionally BUGs on any error returned from
__finish_chunk_alloc() so there's no need for two BUG_ON lines. Remove the
one from __finish_chunk_alloc().
