-Subject: [PATCH] drm/vc4: hdmi: Add container_of macros for encoders
- and connectors
-
-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.
