From 01aad3f0de67281f099e253b404fe08db2814c28 Mon Sep 17 00:00:00 2001 From: Alexander Gordeev Date: Mon, 21 Apr 2014 17:19:31 +0200 Subject: [PATCH] skd: Use pci_enable_msix_exact() instead of pci_enable_msix_range() Function pci_enable_msix_exact() is a variation of pci_enable_msix_range() that allows a device driver to request a particular number of MSI-X interrupts, rather than any number within a specified range.
