commit 94b179052f95c294d83e9c9c34f7833cf3cd4305 upstream. Prox-out events may not be reliably sent by some AES firmware. This can cause problems for users, particularly due to arbitration logic disabling touch input while the pen is in prox. This commit adds a timer which is reset every time a new prox event is received. When the timer expires we check to see if the pen is still in prox and force it out if necessary. This is patterend off of the same solution used by 'hid-letsketch' driver which has a similar problem.

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.
