[PATCH net-next 09/35] cxgb4vf: Use pci_enable_msix_range() instead of pci_enable_msix()

From: Alexander Gordeev
Date: Tue Feb 18 2014 - 05:08:03 EST


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() and pci_enable_msix_range()
interfaces.
