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
