which has two serial and one parallel port, driven by parport_serial.
The reason is, that this commit adds the PCI ID to 8250_pci, when it
was handled by parport_serial before.
In my case (openSUSE kernel), 8250 is built in and parport_serial is
built as a module. Unfortunately with the device occupied by 8250,
parport_serial finds no device and thus does not drive the parport.
I bisected this in the stable series after the openSUSE kernel update
(which pulled in the stable kernel update) broke my printing.
Actually the above commit is totally unnecessary: the serial ports
work very well without it, they are just driven by another driver.
Can this please be reverted? I can't see which problem it solves, but
it definitely breaks the additional ports on my multi-i/o board.
Best regards,
Stefan
