Whenever the code needs to access the vc4_hdmi structure from a DRM connector or encoder, it first accesses the drm_device associated to the connector, then retrieve the drm_dev private data which gives it a pointer to our vc4_dev, and will finally follow the vc4_hdmi pointer in that structure. That will also give us some trouble when having multiple controllers, but now that we have our encoder and connector structures that are part of vc4_hdmi, we can simply call container_of on the DRM connector or encoder and retrieve the vc4_hdmi structure directly.

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.
