From: Quinn Tran <quinn.t...@qlogic.com>

This patch has been added to the 3.18 stable tree. If you have any
objections, please let us know.

===============

[ Upstream commit 84e32a06f4f8756ce9ec3c8dc7e97896575f0771 ]

As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range()  or pci_enable_msi_exact()
and pci_enable_msix_range() or pci_enable_msix_exact()
interfaces.

Log message code 0x00c6 preserved, although it is reported
after successful call to pci_enable_msix_range(), not before
possibly unsuccessful call to pci_enable_msix(). Consumers
of the error code should not notice the difference.
