       pci_bus_read_config_byte -  read a byte from a pci device


       int  pci_bus_read_config_byte (struct pci_bus *bus, unsigned int devfn,
       int where, u8 *value);


       bus          pointer to the parent bus of the pci device to read from

       devfn        the device / function of the pci device to read from

       where        the location in the pci address space to read from

       value        pointer to where to place the data read


       Like pci_read_config_byte but works for pci devices that do not have  a
       pci_dev structure set up yet.  Returns 0 on success.
