Merge tag 'pci-v4.4-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI bugfix from Bjorn Helgaas:
"Here's another fix for v4.4.

This fixes 32-bit config reads for the HiSilicon driver. Obviously
the driver is completely broken without this fix (apparently it
actually was tested internally, but got broken somehow in the process
of upstreaming it).

Summary:

HiSilicon host bridge driver
Fix 32-bit config reads (Dongdong Liu)"

* tag 'pci-v4.4-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci:
