Subject: [PATCH 0/6] PCI: Fix class code usage
Date: Fri, 19 Jun 2015 17:42:15 -0500 [thread overview]
Message-ID: <20150619223325.14626.66402.stgit@bhelgaas-glaptop2.roam.corp.google.com> (raw)
PCI class code management is confusing. The pci_dev.class element contains
a three-byte value: base class/sub-class/interface.
The PCI_BASE_CLASS_* definitions are a single byte, i.e., dev->class >> 16.
The PCI_CLASS_* definitions are either two or three bytes, i.e., either
dev->class >> 8 or just dev->class.
We had several places where we used a two-byte PCI_CLASS_* definition but
forgot to shift it to the right place. These patches fix that for NCR
53c810, TI816X, and Intel USB devices.

Bjorn Helgaas (6):
PCI: Use PCI_CLASS_SERIAL_USB instead of bare number
PCI: Fix generic NCR 53c810 class code quirk
PCI: Fix TI816X class code quirk
PCI: Fix Intel generic reset quirk class code check
PCI: Simplify reset_intel_generic_dev()
PCI: Shift PCI_CLASS_NOT_DEFINED consistently with other classes
