Subject: PCI: altera: Request host bridge window resources with core function
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=74462284bdda85216c3cf49d52920d4164f47e80;p=linux-beck.git

PCI: altera: Request host bridge window resources with core function

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.
