[PATCH v1 18/25] PCI: mvebu: Request host bridge window resources with core function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use devm_request_pci_bus_resources() to request host bridge window
resources instead of doing it by hand in the driver.

No functional change intended.
