Subject[PATCH 69/89] drm/vc4: hdmi: Pass vc4_hdmi to CEC code
Date
Our CEC code also retrieves the associated vc4_hdmi by setting the
vc4_dev pointer as its private data, and then dereferences its vc4_hdmi
pointer.

In order to eventually get rid of that pointer, we can simply pass the
vc4_hdmi pointer directly.
