Subject: [PATCH] mailbox: Remove WARN_ON for async_cb.cb in cmdq_exec_done
Git-commit: ce1537fe288469bf68ee0aabdb860a790b4755ef
Patch-mainline: v5.16-rc1
References: git-fixes

Because mtk_drm_crtc_update_config is not using cmdq_pkt_flush_async,
it won't have pkt->async_cb.cb anymore.

So remove the WARN_ON check of pkt->async_cb.cb at cmdq_exec_done.
