Dan Carpenter 2361bfb055 mmc: block: blk-mq: Potential NULL deref on mmc_blk_alloc_req() failure ...

mmc_blk_alloc_req() is supposed to return error pointers but there is
one path where we forget to set the error code and accidentally return
NULL.  The callers are not expecting that and will have a NULL pointer
dereference.
