Currently the platform filter cannot access any driver-specific state which forces drivers installing a i8042 filter to have at least some kind of global pointer for their filter. Allow callers of i8042_install_filter() to submit a context pointer which is then passed to the i8042 filter. This frees drivers from the responsibility of having to manage this global pointer themself. Also introduce a separate type for the i8042 filter (i8042_filter_t) so that the function definitions can stay compact. Tested on a Dell Inspiron 3505.

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 reStructuredText 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.
