## Description

In the Linux kernel, the following vulnerability has been resolved:  nvmet: use the local P2P device on metadata allocation failure  nvmet_req_alloc_p2pmem_sgls() assigns req->p2p_dev only after the data and metadata SGL allocations succeed. If the data allocation succeeds but the metadata allocation fails, out_free_sg passes req->p2p_dev to pci_p2pmem_free_sgl() before that assignment has taken place.  Pass the local p2p_dev argument instead, so cleanup uses the same PCI device as the successful data allocation.
