Subject: [PATCH] drm/vc4: hdmi: Simplify the connector state retrieval
|
|
|
|
When we have the entire DRM state, retrieving the connector state only
|
|
requires the drm_connector pointer. Fortunately for us, we have
|
|
allocated it as a part of the vc4_hdmi structure, so we can retrieve get
|
|
a pointer by simply accessing our field in that structure.
