Subject: [PATCH 6/9] media: platform: mtk-mdp3: drop calling cmdq_pkt_finalize()
Date: Thu, 15 Feb 2024 00:49:28 +0000

Because client driver has the information of struct cmdq_client, so
it's not necessary to store struct cmdq_client in struct cmdq_pkt.
cmdq_pkt_finalize() use struct cmdq_client in struct cmdq_pkt, so it's
going to be abandoned. Therefore, use cmdq_pkt_eoc() and cmdq_pkt_nop()
to replace cmdq_pkt_finalize().
