Merge branch 'pci/resources'
- Restore VF resizable BAR state after reset (Michał Winiarski)
- Add pci_resource_num_to_vf_bar() and pci_resource_num_from_vf_bar() to
convert between VF BAR number and the dev->resource[] index (Michał
Winiarski)
- Allow IOV resources (VF BARs) to be resized (Michał Winiarski)
- Add pci_iov_vf_bar_set_size() so drivers can control VF BAR size (Michał
Winiarski)
* pci/resources:
PCI/IOV: Allow drivers to control VF BAR size
PCI/IOV: Check that VF BAR fits within the reservation
PCI/IOV: Allow IOV resources to be resized in pci_resize_resource()
PCI/IOV: Add pci_resource_num_to_vf_bar() to convert VF BAR number to/from IOV resource
PCI/IOV: Restore VF resizable BAR state after reset
