[v4] Remove cl in struct cmdq_pkt

[PATCH v4 2/3] media: platform: mtk-mdp3: Use cmdq_pkt_create() and cmdq_pkt_destroy()

Posted by Chun-Kuang Hu 2 months, 1 week ago

Use cmdq_pkt_create() and cmdq_pkt_destroy() common function
instead of implementing mdp3 version.

cmdq_pkt_create does not set the callback. Why doesn't that break things?
Same holds for the crtc driver that is already in linux-next.

This series is to remove pkt->cl.
For the helper function whick need pkt->cl, add parameter to pass the cmdq_client information.
Up to now, only cmdq_pkt_finalize() use pkt->cl, but it is replaced by cmdq_pkt_eoc() and cmdq_pkt_jump_rel() in [PATCH v4 1/3].
So this would not break any thing.

CK
