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.
