From bbd234b146a158ae59da0592c1598336db63b0fc Mon Sep 17 00:00:00 2001 From: Chunhe Lan Date: Fri, 2 Aug 2013 16:46:25 +0800 Subject: [PATCH] powerpc/pci: Change the DECLARE_PCI_FIXUP_{HEADER => EARLY} macro of pci quirk Freescale platform has class code = 0x0b2000, when it boots. This makes kernel PCI bus code to setup these devices resulting into the following notice information when trying to enable them: pci 0000:00:00.0: ignoring class 0x0b2000 (doesn't match header type 01) The above information is outputted by judging value of dev->class before pci_setup_device() function, and the DECLARE_PCI_FIXUP_HEADER quirk runs after pci_setup_device() function. But the DECLARE_PCI_FIXUP_EARLY quirk runs before judging value of dev->class and pci_setup_device() function. So we use the DECLARE_PCI_FIXUP_EARLY macro to fix this issue.
