Subject: [PATCH 0/5] Revert series "CMDQ refinement of Mediatek DRM driver"

Commit c1ec54b7b5af
("drm/mediatek: Use mailbox rx_callback instead of cmdq_task_cb")
would cause numerous mtk cmdq mailbox driver warning:

WARNING: CPU: 0 PID: 0 at drivers/mailbox/mtk-cmdq-mailbox.c:198
cmdq_task_exec_done+0xb8/0xe0

So revert that patch and all the patches depend on that patch.

Chun-Kuang Hu (5):
  Revert "drm/mediatek: Clear pending flag when cmdq packet is done"
  Revert "drm/mediatek: Add cmdq_handle in mtk_crtc"
  Revert "drm/mediatek: Detect CMDQ execution timeout"
  Revert "drm/mediatek: Remove struct cmdq_client"
  Revert "drm/mediatek: Use mailbox rx_callback instead of cmdq_task_cb"
