Subject: [PATCH] drm/vc4: hdmi: Pass vc4_hdmi to CEC code
|
|
|
|
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.
|
|
