PCI: Fix generic NCR 53c810 class code quirk
In the generic quirk fixup_rev1_53c810(), added by a5312e28c195 ("[PATCH] PCI: NCR 53c810 quirk"), we assigned "class = PCI_CLASS_STORAGE_SCSI". But PCI_CLASS_STORAGE_SCSI is only the two-byte base class/sub-class and needs to be shifted to make space for the low-order interface byte. Furthermore, we had a similar quirk, pci_fixup_ncr53c810(), for arch/x86, which assigned class correctly. The arch code is linked before the PCI core, so arch quirks run before generic quirks. Therefore, on x86, the x86 arch quirk ran first, and the generic quirk did nothing because it saw that dev->class was already set. But on other arches, the generic quirk set the wrong class code. Fix the generic quirk to set the correct class code and remove the now-unnecessary x86-specific quirk. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> CC: Matthew Wilcox <matthew@wil.cx>
