Subject: [PATCH v2 12/12] soc: mediatek: cmdq: Remove cmdq_pkt_finalize() helper function
Date: Thu, 22 Feb 2024 15:41:20 +0000
Message-Id: <20240222154120.16959-13-chunkuang.hu@kernel.org>

In order to have fine-grained control, use cmdq_pkt_eoc() and
cmdq_pkt_jump_rel() to replace cmdq_pkt_finalize().
