Hi,
I've noticed that after the 'class' field there are 3 u8 fields. If you
add the revision there then sizeof(struct pci_dev) stays constant:
diff --git a/include/linux/pci.h b/include/linux/pci.h
index 09be0f8..c8586b7 100644
--- a/include/linux/pci.h
+++ b/include/linux/pci.h
@@ -124,6 +124,7 @@ struct pci_dev {
unsigned short subsystem_vendor;
unsigned short subsystem_device;
unsigned int class; /* 3 bytes: (base,sub,prog-if) */
+ u8 revision; /* PCI revision id */
u8 hdr_type; /* PCI header type (`multi' flag masked out) */
u8 rom_base_reg; /* which config register controls the ROM */
u8 pin; /* which interrupt pin this device uses */
