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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.

If aux->transfer == NULL, then just return without doing anything. In that case the function is likely called for a non-(e)DP connector. This never happened for the i915 driver, but the nouveau and amdgpu drivers need this check. The alternative would be to add this check in those drivers before every drm_dp_cec call, but it makes sense to check it in the drm_dp_cec functions to prevent a kernel oops.
