[PATCH v3] serial: exar: Add support for Sealevel 7xxxC serial cards

[Matthew Howell]

From: Matthew Howell <matthew.howell@sealevel.com>

Add support for Sealevel 7xxxC serial cards.

This patch:
* Adds IDs to recognize 7xxxC cards from Sealevel Systems.
* Updates exar_pci_probe() to set nr_ports to last two bytes of primary
dev ID for these cards.

Signed-off-by: Matthew Howell <matthew.howell@sealevel.com>
---

v2: Moved "This patch..." above signed-off line.
v3: "Added From: Matthew Howell <matthew.howell@sealevel.com>" to
submission.

Let me know if I need to make any more changes.

Hi,

This is the friendly patch-bot of Greg Kroah-Hartman.  You have sent him
a patch that has triggered this response.  He used to manually respond
to these common problems, but in order to save his sanity (he kept
writing the same thing over and over, yet to different people), I was
created.  Hopefully you will not take offence and will fix the problem
in your patch and resubmit it so that it can be accepted into the Linux
kernel tree.

You are receiving this message because of the following common error(s)
as indicated below:

- Your patch is malformed (tabs converted to spaces, linewrapped, etc.)
  and can not be applied.  Please read the file,
  Documentation/process/email-clients.rst in order to fix this.

If you wish to discuss this problem further, or you have questions about
how to resolve this issue, please feel free to respond to this email and
Greg will reply once he has dug out from the pending patches received
from other developers.

thanks,

greg k-h's patch email bot
