Merge tag 'pci-v3.19-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI fixes from Bjorn Helgaas:
"These are fixes for:
- a resource management problem that causes a Radeon "Fatal error
during GPU init" on machines where the BIOS programmed an invalid
Root Port window. This was a regression in v3.16.
- an Atheros AR93xx device that doesn't handle PCI bus resets
correctly. This was a regression in v3.14.
- an out-of-date email address"
