From 2921d1790eeeaf574df94fc5b1aa066e7d86d8f7 Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Thu, 9 Jul 2015 16:00:38 +0800 Subject: [PATCH] powerpc/PCI: Use for_pci_msi_entry() to access MSI device list Use accessor for_each_pci_msi_entry() to access MSI device list, so we could easily move msi_list from struct pci_dev into struct device later.
