Comedi drivers can initialize an 8255 subdevice in I/O space by calling `subdev_8255_init()`, or in memory-mapped I/O space by calling `subdev_8255_mm_init()`, or by supplying a call-back function pointer and context to either of those functions. Change it so that a new function `subdev_8255_cb_init()` shall be called instead when supplying a callback function and context, and remove the call-back function parameter from `subdev_8255_init()` and `subdev_8255_mm_init()`. Also rename `subdev_8255_init()` to `subdev_8255_io_init()`. The parameters are changing, so might as well rename it at the same time. Also rename the `regbase` member of `struct subdev_8255_private` to `context` since this holds the context for the call-back function call.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
