From 5e37f67063a14450f1fff3baee81efe7c146592a Mon Sep 17 00:00:00 2001 From: Alexander Gordeev Date: Thu, 13 Mar 2014 11:23:37 +1030 Subject: [PATCH] virtio: Use pci_enable_msix_exact() 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() or pci_enable_msi_exact() and pci_enable_msix_range() or pci_enable_msix_exact() interfaces.
