The Comedi "comedi_isadma.h" header is included by the source for the
"comedi_isadma" helper module and other modules that use it. It does
not compile cleanly when it is the first header file included. It uses
the `dma_addr_t` type, so include <linux/types.h> to declare it. (Also,
that indirectly takes care of the use of `NULL`.) It uses `struct
comedi_device *` in various function prototypes, so add an incomplete
declaration of `struct comedi_device`.

The Comedi "comedi_8254.h" header file is included by various Comedi
drivers with timer/counters based on the 8254 chip. The drivers do not
compile cleanly if this header file is included first. It uses pointers
to the `struct comedi_device`, `struct comedi_subdevice`, and `struct
comedi_insn` structures in various function prototypes, so declare those
as incomplete types. It use the `bool` type, so include
<linux/types.h>. It also uses the `__iomem` tag, but that seems to be
taken care of indirectly by including <linux/types.h>.

The Comedi "addi_watchdog.h" header doesn't use anything form

don't bother including the header file.

The Comedi "8255" module is both a standalone Comedi device driver
module for simple devices with one or more 8255 "Programmable Peripheral
Interface" chips at known I/O base addresses (configured at run-time),
and a helper module to configure a 8255-based digital I/O subdevice for
other Comedi drivers.
Split the "8255 subdevice helper" functionality into a new module:
"comedi_8255", leaving the standalone 8255 Comedi driver in the "8255"
module.
The Comedi "detach" routine of the standalone "8255" driver needs to
retrieve the I/O base address passed to the "comedi_8255" module to set
up each subdevice in order to release the I/O port regions it requested
in its "attach" routine. The "comedi_8255" module stores it in a
"subdevice private" data structure that is no longer known to the "8255"
module, so add a new, exported function `subdev_8255_regbase()` to
retrieve it.

Several Comedi driver modules call `subdev_8255_init()` or
`subdev_8255_mm_init()` to set up a digital I/O subdevice based on the
"8255" chip. One of the parameters to these functions is an optional
pointer to an I/O callback function to perform the actual register
accesses (an internal default callback function is used if NULL).
The kerneldoc for `subdev_8255_init()` and `subdev_8255_mm_init()`
describe the prototype of the optional I/O callback function
incorrectly (my fault), adding a non-existent parameter of type `struct
comedi_subdevice *`. Fix the kerneldoc. Also add parameter names to
the callback function pointer type wherever it occurs to make the usage
clearer.

The Comedi "8255" driver does not clean up properly on failure. It can
leave requested I/O port regions unreleased. Specifically, the Comedi
"attach" handler (`dev_8255_attach()`) requests a specified I/O port
region before calling `subdev_8255_init()` to set up the subdevice. If
that fails, the "attach" handler returns an error and the Comedi core
will call the "detach" handler (`dev_8255_detach()`) to clean up. The
"detach" handler is responsible for releasing the I/O port regions
successfully requested by the "attach" handler. Unfortunately, it is
unable to obtain the base address of the region if the call to
`subdev_8255_init()` failed.
Fix the I/O region leak by releasing the region in the "attach" handler
directly if the call to `subdev_8255_init()` fails.

The code for determining which board type matches the PCI device ID is
over-the-top since only a single board type is supported. Also, the
method it uses match the PCI device ID to a board type is a little
antiquated. Most comedi drivers for PCI devices use `driver_data` from
the probed PCI device as an index into an array of supported board
types, but "gsc_hpdi" uses a `for` loop to find an element of
`hpdi_boards[]` that matches the PCI device. The only thing in
`hpdi_boards[]` not used for finding a matching PCI device is the `name`
member of `struct hpdi_board` which points to a string literal and ends
up getting assigned to `dev->board_name`.
Get rid of the multiple board type support, and set `dev->board_name` to
point to the original string literal pointed to by
`hpdi_boards[0].name`. This string is visible to userspace.
