Hi all,

After merging the btrfs tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

fs/btrfs/check-integrity.c: In function 'btrfsic_process_superblock_dev_mirror':
fs/btrfs/check-integrity.c:916:9: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized]
  916 |  return ret;
      |         ^~~

Introduced by commit

  5a03d907a555 ("btrfs: remove buffer_heads form super block mirror integrity checking")

I think this is not a false positive since ret is only assigned is a
"goto out" is executed.
