- 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.
