From 45c64b6ac4ef0f50ba754e997585c02b10c93c02 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 6 Jun 2016 15:47:24 -0500 Subject: [PATCH] PCI: tegra: 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.
