The first patch in this series introduces the following 4 helper functions to
the PCI core:
* pci_request_mem_regions()
* pci_request_io_regions()
* pci_release_mem_regions()
* pci_release_io_regions()
which encapsulate the request and release of a PCI device's memory or I/O
bars.
The subsequent patches convert the drivers, which use the
pci_request_selected_regions(pdev,
pci_select_bars(pdev, IORESOURCE_MEM), name);
and similar pattern to use the new interface.
This was suggested by Christoph Hellwig in
http://lists.infradead.org/pipermail/linux-nvme/2016-May/004570.html and
tested on kernel v4.6 with NVMe.
The conversion of the drivers has been performed by the following coccinelle
spatch:

Changes since v1:
* Fixed indendatoin in pci.h patch to not cross the 80 chars boundary.
* Split Ethernet patches into two, one for Atheros and one for Intel drivers.
* Correctly named lpfc patch.
* Converted init-path of lpfc driver as well.
* Added Reviewed-by tags were appropriate.

Add helpers to request and release a device's memory or I/O regions.
With these helpers in place, one does not need to select a device's memory or
I/O regions with pci_select_bars() prior to requesting or releasing them.
