Ugh, this is due to this code:

#define INTEL_VGA_DEVICE(id, info) {		\
	0x8086,	id,				\
	~0, ~0,					\
	0x030000, 0xff0000,			\
	(unsigned long) info }

#define INTEL_QUANTA_VGA_DEVICE(info) {		\
	0x8086,	0x16a,				\
	0x152d,	0x8990,				\
	0x030000, 0xff0000,			\
	(unsigned long) info }


Which really should be using the normal pattern for defining these
structs:

#define PCI_DEVICE_CLASS(dev_class,dev_class_mask) \
        .class = (dev_class), .class_mask = (dev_class_mask), \
        .vendor = PCI_ANY_ID, .device = PCI_ANY_ID, \
        .subvendor = PCI_ANY_ID, .subdevice = PCI_ANY_ID

The warning is also not a real issue, just clang being overzealous.
