In certain cases we need a variant of pci_read_vpd()/pci_write_vpd() that does not check against dev->vpd.len. Such cases are: - reading VPD if dev->vpd.len isn't set yet (in pci_vpd_size()) - devices that map non-VPD information to arbitrary places in VPD address space (example: Chelsio T3 EEPROM write-protect flag) Therefore add function variants that check against PCI_VPD_MAX_SIZE only. Make the cxgb3 driver the first user of the new functions. Preferably this series should go through the PCI tree.
