[PATCH net-next 35/35] wil6210: Use pci_enable_msi_range() instead of pci_enable_msi_block()
From: Alexander Gordeev
Date: Tue Feb 18 2014 - 05:11:53 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.
