From 12eb21de1f26233ad195ffe991697d61790f4193 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 12 Jul 2016 18:20:15 +0900 Subject: [PATCH] PCI: Switch msix_program_entries() to use pci_msix_desc_addr() Instead of relying on the msix_entry structure for the vector number, read it from the msi_desc.
