PCI: Add quirk for setting valid class for TW6869 frame grabber
Based on commit d4ab3dedc3be1a033420de9daf03056f949c4e51 (PCI: Add quirk for setting valid class for TI816X Endpoint) Having class code = 0 makes kernel PCI bus code skip allocating BARs to these devices resulting in the following error: PCI: Device 0000:01:00.0 not available because of resource collisions This patch adds a ID specific (0x1797:6869) early fixup quirk to replace class code with PCI_CLASS_MULTIMEDIA_VIDEO.
