From f3c9407bc201f2e3f0e6845e9921454945568ed1 Mon Sep 17 00:00:00 2001 From: Alexander Gordeev Date: Tue, 18 Feb 2014 11:11:48 +0100 Subject: [PATCH] mlx5: 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.
