Subject: [PATCH 2/5] xhci: Use pci_enable_msix_exact() instead of pci_enable_msix()

From: Alexander Gordeev <agordeev@...hat.com>

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.
