Merge branch 'pci/p2pdma'

- Free struct p2p_pgmap, not a member within it, in the
  pci_p2pdma_add_resource() error path (Sungho Kim)

- Make pci_has_p2pmem() static (Leon Romanovsky)

* pci/p2pdma:
  PCI/P2PDMA: Reduce scope of pci_has_p2pmem()
  PCI/P2PDMA: Fix incorrect pointer usage in devm_kfree() call
