Subject: [PATCH] drm/vc4: Add correct stop condition to
|
|
vc4_dsi_encoder_disable iteration
|
|
|
|
vc4_dsi_encoder_disable is partially an open coded version of
|
|
drm_bridge_chain_disable, but it missed a termination condition
|
|
in the loop for ->disable which meant that no post_disable
|
|
calls were made.
|
|
|
|
Add in the termination clause.
