Hello Russel,
Some soft modem pci devices (known list in the patch) claim to have
'communication' class, and as result they are grabbed by serial driver.
Actually those devices are useless for serial drivers (it is not "real"
modem and doesn't have serial interface), but this prevents probing from
soft modem drivers (there are few in ALSA).
The patch below makes it possible to define ids of such known non-serial
devices and don't probe it by 8250_pci driver.
Thanks,
Sasha.
