+ * Read a byte from the SPD. 
+ *
+ * For this chip, that is really just saying 'read a byte from smbus'.
+ * So we use smbus_read_byte. Nota Bene: leave this here as a function 
+ * rather than a #define in an obscure location. This function is called 
+ * only a few dozen times, and it not performance critical. 
+ *
+ * @param device The device.
+ * @param address The address.
+ * @return The data from the SMBus packet area or an error of 0xff (i.e. -1).
