Based on similar work for an older kernel in the Grsecurity patch.

It used to be a gap in port definitions after PORT_MAX_8250. Since the
new drivers are coming the gap become shorter and shorter until the
commit a2d6a987bfe4 ("serial: 8250: Add new port type for TI DA8xx/66AK2x")
completely removed it.

So, while type here is just a formality, make things a little bit more
explicit for this driver and move port types to UAPI header. Note,
it uses two types for now.

There is no need to do a NULL check for debugfs_remove().

Quoting Documentation/filesystems/debugfs.txt:

"The dentry value can be NULL, in which case nothing will be removed."

, so remove the unneeded NULL check.

Pull tty and serial updates from Greg KH:
 "Here is the big tty and serial patch set for 4.9-rc1.

  It also includes some drivers/dma/ changes, as those were needed by
  some serial drivers, and they were all acked by the DMA maintainer.

  Also in here is the long-suffering ACPI SPCR patchset, which was
  passed around from maintainer to maintainer like a hot-potato. Seems I
  was the sucker^Wlucky one. All of those patches have been acked by the
  various subsystem maintainers as well.

  All of this has been in linux-next with no reported issues"

Check for uart_ops structures that are only stored in the ops field of a
uart_port structure.  This field is declared const, so uart_ops structures
that have this property can be declared as const also.

The semantic patch that makes this change is as follows:

The DMA is a function 0 of the multifunction device where SPI host is attached.
Thus, we may avoid to hardcode PCI slot number.
