[PATCH 0/3] Misc fixes silencing false positives from cppcheck

[Johannes Thumshirn <jth@kernel.org>]

misc fixes provoked by https://bugzilla.kernel.org/show_bug.cgi?id=205003

The first patch removes an unneeded variable, which when removed silences
a false positive warning generated by cppcheck.

The second patch removes a BUG_ON() which can't be hit, for the same
reasons as there can't be no NULL-pointer dereference in patch 1.

Patch number three removes a WARN_ON() which can't be triggered. This
WARN_ON() was also identified as a possible NULL-pointer dereference by
cppcheck.


Johannes Thumshirn (3):
  btrfs: fix possible NULL-pointer dereference in integrity checks
  btrfs: remove superfluous BUG_ON() in integrity checks
  btrfs: remove impossible WARN_ON in btrfs_destroy_dev_replace_tgtdev()
