From 18fce3c440c762ab4dfb6156bbd3c0beb0f67f17 Mon Sep 17 00:00:00 2001 From: Alexander Gordeev Date: Mon, 18 Aug 2014 08:01:42 +0200 Subject: [PATCH] hpsa: 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() or pci_enable_msi_exact() and pci_enable_msix_range() or pci_enable_msix_exact() interfaces.
