Hi,
this doesn't build:

drivers/media/platform/mediatek/mdp3/mtk-mdp3-cmdq.c: In function ‘mdp_auto_release_work’:
drivers/media/platform/mediatek/mdp3/mtk-mdp3-cmdq.c:504:29: error: passing argument 1 of ‘cmdq_pkt_destroy’ from incompatible pointer type [-Werror=incompatible-pointer-types]
  504 |         cmdq_pkt_destroy(mdp->cmdq_clt, &cmd->pkt);
      |                          ~~~^~~~~~~~~~
      |                             |
      |                             struct cmdq_client **

      |                       ~~~~~~~~~~~~~~~~~~~~^~~~~~

Same in other instances in this patch and in other patches in the series.

Thanks,
