Oops. Also in other drivers :(
I will fix up the messages for the v2 series, which will not going to include
the patch against 8250_dma.

If I understand things right around the 8250_* is that the
serial8250_request_dma() which is called from serial8250_do_startup() is not
called at module probe time, so it can not be used to handle deferred probing.

Thus this patch can be dropped IMO.
