Originally, normal dai link fixup callback is overwritten by sof fixup
callback on mtk_sof_card_late_probe and it relies on the mapping defined
on struct sof_conn_stream.
It's not flexible. When a new hardware connection is adopted, user needs
to update struct sof_conn_stream defined in machine driver which is used
to specify the mapping relationship of normal BE and SOF BE.
In the patch, mtk_sof_check_tplg_be_dai_link_fixup() is introduced for
all normal BEs. In mtk_sof_late_probe, back up normal BE fixup if it
exists and then overwrite be_hw_params_fixup by the new callback.
There are two cases for FE and BE connection.
case 1:
SOF FE -> normal BE
-> SOF_BE
case 2:
normal FE -> normal BE
In the new fixup callback, it tries to find SOF_BE which connects to the
same FE, and then reuses the fixup of SOF_BE. If no SOF_BE exists,
it must be case 2, so rollback to the original fixup if it exists.
As a result, the predefined relation is not needed anymore. Hardware
connection can be controlled by the mixer control for AFE interconn.
Then, DPCM finds the BE mapping at runtime.

Please, lowercase labels... or you can avoid gotos entirely:
ret = mtk_sof_find_tplg_be_dai_link(...)
if (ret == 0 && sof_dai_link) {
if (sof_priv->sof_dai_link_fixup)

return dai_link->be_hw_params_fixup(rtd, params);
else
break;

}
}
return 0;

P.S.: I'm truly sorry for not noticing that before!
