The already fixed bug in SDL only affected conditional effects. This should fix FFB in Forza Horizion 4/5 on Moza Devices as Forza Horizon flips the constant force direction instead of using negative magnitude values. Changing the direction in the effect directly in pidff_upload_effect() would affect it's value in further operations like comparing to the old effect and/or just reading the effect values in the user application. This, in turn, would lead to constant PID_SET_EFFECT spam as the effect direction would constantly not match the value that's set by the application. This way, it's still transparent to any software/API. Only affects conditional effects now so it's better for it to explicitly state that in the name. If any HW ever needs fixed direction for other effects, we'll add more quirks.

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.
