Matthias Kaehlcke 0a1dc6377a dm: verity-loadpin: Add NULL pointer check for 'bdev' parameter 
commit 47f04616f2c9b2f4f0c9127e30ca515a078db591 upstream.

Add a NULL check for the 'bdev' parameter of
dm_verity_loadpin_is_bdev_trusted(). The function is called
by loadpin_check(), which passes the block device that
corresponds to the super block of the file system from which
a file is being loaded. Generally a super_block structure has
an associated block device, however that is not always the
case (e.g. tmpfs).

Cc: stable@vger.kernel.org # v6.0+
Fixes: b6c1c5745ccc ("dm: Add verity helpers for LoadPin")
