blk-integrity: checking for NULL instead of IS_ERR
We recently changed bio_integrity_alloc() to return ERR_PTRs instead of NULL but these calls were missed. Fixes: 06c1e3902aa7 ('blk-integrity: empty implementation when disabled') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Reviewed-by: Johannes Thumshirn <jthumshirn@suse.de> Signed-off-by: Jens Axboe <axboe@fb.com>
