From 4efe52bf23c96cee7052273bd8549caee4d0fdc2 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 12 Nov 2014 18:26:49 -0700 Subject: pci: Honour pci_skip_dev() When enumerating devices, honour the pci_skip_dev() function. This can be used by PCI controller drivers to restrict which devices will be probed. This is required by the NVIDIA Tegra PCIe controller driver, which will fail with a data abort exception if an access is attempted to a device number larger than 0 outside of bus 0. pci_skip_dev() is therefore implemented to prevent any such accesses.
