Subject: [PATCH] drm/vc4: crtc: Rework the encoder retrieval code
|
|
(again)
|
|
|
|
It turns out the encoder retrieval code, in addition to being
|
|
unnecessarily complicated, has a bug when only the planes and crtcs are
|
|
affected by a given atomic commit.
|
|
|
|
Indeed, in such a case, either drm_atomic_get_old_connector_state or
|
|
drm_atomic_get_new_connector_state will return NULL and thus our encoder
|
|
retrieval code will not match on anything.
|
|
|
|
We can however simplify the code by using drm_for_each_encoder_mask, the
|
|
drm_crtc_state storing the encoders a given CRTC is connected to
|
|
directly and without relying on any other state.
|
