Instead of stack allocating the cmdq_client and cmdq_handle structures
switch them to pointers, allowing us to migrate this driver to use the
common functions provided by mtk-cmdq-helper.
In order to do this, it was also necessary to add a `priv` pointer to
struct cmdq_client, as that's used to pass (in this case) a mtk_crtc
handle to the ddp_cmdq_cb() mailbox RX callback function.

I think removing ifdefs and using helper function are different things. You could remove ifdefs and keep mtk_drm_cmdq_pkt_create(). Regards, CK > > Regards, > Angelo >

And this is related to different maintainer's tree. So it would be a long time to process. For you, only removing ifdes is urgent, so use cmdq_pkt_create() is not urgent. So let's keep mtk_drm_cmdq_pkt_create() and you could remove ifdefs. Regards, CK > > > > Regards, > > CK > > > > > > > > Regards, > > > Angelo > > > > >
