blk-mq: pass along blk_mq_alloc_tag_set return values
Two of the blk-mq based drivers do not pass back the return value from blk_mq_alloc_tag_set, instead just returning -ENOMEM. blk_mq_alloc_tag_set returns -EINVAL if the number of queues or queue depth is bad. -ENOMEM implies that retrying after freeing some memory might be more successful, but that won't ever change in the -EINVAL cases. Change the null_blk and mtip32xx drivers to pass along the return value. Signed-off-by: Robert Elliott <elliott@hp.com> Signed-off-by: Jens Axboe <axboe@fb.com>
