This resulted in an empty output bitstream when using the MDP from userspace, as well as the following errors: mtk-mdp3 14001000.dma-controller: Uninit component inner id 4 mtk-mdp3 14001000.dma-controller: mdp_path_ctx_init error 0 mtk-mdp3 14001000.dma-controller: CMDQ sendtask failed: -22 Add the missing compatible to the array to restore functionality.
