Honestly I don't really like these mini accessor functions as well.
But when using a union we loose all the benefits of the enums as
drivers still can touch the compound result value.
I like Hannes' idea of gettting rid of clear_scsi_result() and use
set_scsi_result() for it. This way we zap one of these
helpers. Actually we could even use it for all and thus could
eliminate all the set_{host,driver,msg}_byte() accessors.
Thanks,
