PATCH 1/1 drivers/serial/8250_pci.c (add support for '8-port RS-232 MIC-3620 from advantech'

Hello

This is my first mail to this list... sorry for all my mistakes

We use a 8-port RS-232 MIC-3620 from advantech (see
http://www.advantech.com/products/8-port-RS-232-Communication-CPCI-Card/mod_1-2MLG80.aspx)
and need linux support for this card.

Can you firstly send me an lspci -vvxxx of that device. Also see Documentation/SubmittingPatches about Signed-off-by lines and we'll sort out merging it.

ok. I don't test this. But you are right. The last entry in pci_serial_quirks should catch it.

This make the patch to a 'add only 5 lines for support of 8 Ports'-Patch. :-)

Should I post a new patch, without this 10 lines?

BTW: there are one other card's with a part like this:
- PCI_DEVICE_ID_PLX_9030

This part is not needed at all, pci_default_setup() will be used by default.
ok. I don't test this. But you are right. The last entry in pci_serial_quirks should catch it.
Should I post a new patch, without this 10 lines?
Yes and add Signed-off-by: line please.

Why not use PCI_VENDOR_ID_ADVANTECH as PCI_SUBVENDOR_ID too?

The Advantech vendor id is not 0x3620. This confused me as well which is why I asked for an lspci. Advantech has stuck the device id in the subvendor bits and '1' in the subdevice (so it should be 1 not PCI_ANY_ID).

Since the name describes a device id where it should be a (sub)vendor id, I would suggest that you add a line of comment to explain the case. So that no one will be tempted to change it back to PCI_VENDOR_ID_ADVANTECH in the future.
