Subject: linux-next: build warning in Linus' tree

Hi Linus,

Building Linus' tree, today's linux-next build (powerpc_ppc64_defconfig)
produced these warnings:

fs/btrfs/backref.c: In function 'find_parent_nodes':
fs/btrfs/backref.c:482:3: warning: 'ret' may be used uninitialized in this function [-Wuninitialized]
fs/btrfs/backref.c:395:6: note: 'ret' was declared here
fs/btrfs/backref.c:381:3: warning: 'ret' may be used uninitialized in this function [-Wuninitialized]
fs/btrfs/backref.c:300:6: note: 'ret' was declared here

and indeed, there is a path through to a BUG_ON(ret) that does not set
"ret".  Introduced by commit 8da6d5815c59 ("Btrfs: added
btrfs_find_all_roots()").
