Subject: [PATCH v4 10/13] soc: mediatek: cmdq: export finalize function
Date: Tue, 3 Mar 2020 18:58:42 +0800 [thread overview]
Message-ID: <1583233125-7827-11-git-send-email-dennis-yc.hsieh@mediatek.com> (raw)
In-Reply-To: <1583233125-7827-1-git-send-email-dennis-yc.hsieh@mediatek.com>
Export finalize function to client which helps append eoc and jump
command to pkt. Let client decide call finalize or not.
