Transform some calls to kmalloc/memset to a single kzalloc (or kcalloc).

Here is a short excerpt of the semantic patch performing
this transformation:

Currently a parport_driver can't get a handle on the device node for the
underlying parport (PNPACPI, PCI, etc).  That prevents correct placement of
sysfs child nodes, which can affect things like power management.

This patch adds a field to "struct parport" pointing to that device node, and
updates non-legacy port drivers to initialize that device pointer.  That field
replaces the analagous PCI-only support in parport_pc.

As can be seen from this patch, the avlab_*_[68]50 table entries are
identical to the plain avlab_* entries in every respect.  Hence, there
is no need to list them separately in the pciserial_board nor
parport_pc_pci card tables - they can re-use the plain avlab_* entries.

Steinar H. Gunderson reported:

  - For some reason, it detects the 9845 as a 9735 -- it appears this is
    simply related to the ordering in parport_serial_pci_tbl[]. If we move
    the 9845 up above the 9735, it prints out 9710:9845, but no change in
    behaviour. (We didn't find out why this was the case; we left it alone
    since it didn't affect our problem.)
  - The card has no parallel port (at least no physical ones), yet it reports
    (via its subsystem ID of 0x0014) one parallel port and four serial ports.
    The probe for the parallel port fails, and the driver just aborts. Thus,
    it doesn't find the serial ports.

Fix the debugging code to use dev_dbg, but don't bother displaying the
PCI ID of the detected board (that's accessible via other means.)

Also, arrange for parport_register() to return 0 even if it finds no
ports.

Convert parport_serial to use the new 8250_pci interface, converting
the table to a pciserial_board table.  This also unuses the SPCI_*
definitions in serialP.h, which can now be removed.

kernel 2.6.12-rc2 adopted some code by Bjorn Helgaas supporting NetMos combo
controller cards. this implementation doesn't work for nm9855 based cards!

there are two reasons:

a) the module 'parport_pc' doesn't want to give the resonsibility for
   the netmos_9855 to 'parport_serial' and can not handle the serial lines
   -- trivial to fix...

   http://lists.infradead.org/pipermail/linux-parport/2005-February/000250.html
   http://lkml.org/lkml/2005/3/24/199 b) the support for the nm9855 in

   'parport_serial' still doesn't work because of wrong assumptions about
   the relevant BARs port address layout for this chip:

	 0000:00:09.0 Communication controller:
         	      NetMos Technology PCI 9855
         	      Multi-I/O Controller (rev 01)
	 	      (= 9710:9855)
         Subsystem: LSI Logic / Symbios Logic 1P4S (= 1000:0014)
  	 Flags: medium devsel, IRQ 177
	 I/O ports at a800 [size=8]  (= parport)
	 I/O ports at a400 [size=8]
	 I/O ports at a000 [size=8]  (= serial)
	 I/O ports at 9800 [size=8]  (= serial)
	 I/O ports at 9400 [size=8]  (= serial)
	 I/O ports at 9000 [size=16] (= serial)

the following patch will fix the problem.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
