nvme-pci: check for NULL return from pci_alloc_p2pmem() Modify nvme_alloc_sq_cmds() to call pci_free_p2pmem() to free the memory it allocated using pci_alloc_p2pmem() in case pci_p2pmem_virt_to_bus() returns null. Makes sure not to call pci_free_p2pmem() if pci_alloc_p2pmem() returned NULL, which can happen if CONFIG_PCI_P2PDMA is not configured. The current implementation is not expected to leak since pci_p2pmem_virt_to_bus() is expected to fail only if pci_alloc_p2pmem() returns null. However, checking the return value of pci_alloc_p2pmem() is more explicit. Signed-off-by: Alan Mikhak <alan.mikhak@sifive.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
