PCI: Fix OF logic in pci_dma_configure()
This patch fixes a bug introduced by previous commit, which incorrectly checkes the of_node of the end-point device. Instead, it should check the of_node of the host bridge. Fixes: 50230713b639 ("PCI: OF: Move of_pci_dma_configure() to pci_dma_configure()") Reported-by: Robin Murphy <robin.murphy@arm.com> Signed-off-by: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Rafael J.
