Merge tag 'pci-v4.4-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI fixes from Bjorn Helgaas:
 "Here are a few fixes I'd like to have in v4.4: a generic one for sysfs
  and three for HiSilicon and DesignWare host controllers.

  Summary:

  NUMA:
   - Prevent out of bounds access in numa_node override (Mathias Krause)

  HiSilicon host bridge driver:
   - Fix deferred probing (Arnd Bergmann)

  Synopsys DesignWare host bridge driver:
   - Remove incorrect io_base assignment (Stanimir Varbanov)
   - Move align_resource function pointer to pci_host_bridge structure
     (Gabriele Paoloni)"
