We should start putting theses discussions on the list so other eventual users will be able to follow our plans, in any case we decided to have those bus type defines in order to encapsulate the bus implementation to the driver. The driver doesn't need to know anything about the bus it should just call a "write" function, and that function would handle all bus specific logic.

Yes. All bus have their function pointer to write, read and ioctl. The driver will try to write and the device will know which bus use.

Good one, now we can use error codes and NULL everywhere.

yes, as this define has more than 1 line, inline will avoid error on using
if without { }.
