Matthias Kaehlcke 52c16b9fb9 dm: verity-loadpin: Add NULL pointer check for 'bdev' parameter
commit 47f04616f2 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).
