Tomasz Pakuła 85123a581f HID: pidff: Convert infinite length from Linux API to PID standard
[ Upstream commit 37e0591fe44dce39d1ebc7a82d5b6e4dba1582eb ]

Software uses 0 as de-facto infinite lenght on Linux FF apis (SDL),
Linux doesn't actually define anythi as of now, while USB PID defines
NULL (0xffff). Most PID devices do not expect a 0-length effect and
can't interpret it as infinite. This change fixes Force Feedback for
most PID compliant devices.

As most games depend on updating the values of already playing infinite
effects, this is crucial to ensure they will actually work.

Previously, users had to rely on third-party software to do this conversion
and make their PID devices usable.

README

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.
