[v3.9] [v3.10] [Regression] serial: 8250_pci: add support for anotherkind of NetMos Technology PCI 9835 Multi-I/O Controller

[Joseph Salisbury]

Hi Wang,

A bug was opened against the Ubuntu kernel[0].  After a kernel bisect,
it was found that reverting the following commit resolved this bug:

commit 8d2f8cd424ca0b99001f3ff4f5db87c4e525f366
Author: Wang YanQing <udknight@xxxxxxxxx>
Date:   Fri Mar 1 11:47:20 2013 +0800

    serial: 8250_pci: add support for another kind of NetMos Technology
PCI 9835 Multi-I/O Controller


The regression was introduced as of v3.9-rc3 and still exists in the
current Mainline tree.  It was also propagated to the stable trees.

The patch causes the device to use the serial module instead of
parport_serial.  Maybe the the quirk in ~drivers/pci/quirks.c
quirk_netmos() needs to be modified?

I see that you are the author of this patch, so I wanted to run this by
you.  I was thinking of requesting a revert, but I wanted to get your
feedback first.


Thanks,

Joe
