From bd66368940ae1c8c7491f55650b813c9d790f92c Mon Sep 17 00:00:00 2001 From: Alexander Gordeev Date: Tue, 18 Feb 2014 11:08:01 +0100 Subject: cxgb4vf: Use pci_enable_msix_range() instead of pci_enable_msix() 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.
