This patch adds a new list to the driver's device structure. The list will keep the file private data structures that the driver creates when a user process opens the device. This change is needed because it is useless to try to count how many FD are open. Instead, track our own private data structure per open file and once it is released, remove it from the list. As long as the list is not empty, it means we have a user that can do something with our device.

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.
