[PATCH 0/4] fs: btrfs: coverity fixes

Most of the coverity reports are at least a good hint to us to improve the code style. Although there are some false alerts, but it's really hard to teach coverity to be a real human (yet), thus fix the warning even it's just false alerts.

Qu Wenruo (4): fs: btrfs: inode: handle uninitialized type before returning it fs: btrfs: volumes: prevent overflow for multiplying fs: btrfs: initialize @ret to 0 to prevent uninitialized return value fs: btrfs: initialize @ii in show_dir() to make coverity happy
