At the moment, only DRM_MODE_ROTATE_180 is allowed when we try to apply the rotation from the video mode parameters. It is also useful to allow DRM_MODE_ROTATE_0 in case there is only a reflect option in the video mode parameter (e.g. video=540x960,reflect_x). DRM_MODE_ROTATE_0 means "no rotation" and should therefore not require any special handling, so we can just add it to the if condition.

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.
