Is "status_byte(cmd->result) == CHECK_CONDITION" short enough for a single
line of code? Is the line splitting really necessary?

Please change (!(x == y)) into (x != y).

Please change (driver_byte(result) == DRIVER_SENSE) into
driver_byte(result) == DRIVER_SENSE.

Same comment here.

Please change (x == y) == 0 into x != y.

Thanks,
