[PATCH 0/2] xfs: fix some sparse warnings.

[Dave Chinner]

The first patch is a new warning from the log recovery ordering code
- I used the wrong structure to pull the superblock LSN out of the
on disk buffer. On most platforms there should be no actual bug here
as both the xfs_sb and xfs_dsb have identical layouts.

The second patch is just fixing a few bits of warning noise that
sparse produces. There's not actual compiled code change from them.
