[BUG] Unable to load tplg with mixer or DRC component

Describe the bug
Unable to load tplg with mixer or DRC component.
This is the dmesg log:

Expected behavior
Tplg is loaded correctly.

Impact
Mixer/DRC not working

Environment

Did a git bisect and the "bad" commit is e847c8b

I have a fix for MIXER - create a ipc_config_mixer struct as we have for volume or src or asrc:

but I'm not sure if is the right one.
Also, for DRC will have to create another structure?

@btian1

@btian1 can you please explain more why this patch was added: e847c8b
There were unanswered questions on the PR as well - https://github.com/thesofproject/sof/pull/7992/files#r1286322041

Another fix I'm trying is to have the SOF_COMP_MIXER as the others:

@lgirdwood

@lgirdwood @singalsu @ujfalusi any ideas
Have you checked mixer with IPC3?

@btian1

I tested DRC module conversion back then with IPC3 and it was working. I don't think new IPC structs should be added since they all follow the generic processing component IPC. Also there should be no need for IPC size adjustments like exception handling. @btian1 can the issue that was fixed by e847c8b be addressed differently?

All IPC3 build has been removed from git main for Intel platforms so we are not able to test it ourselves any more.

Thanks @singalsu
Yes, reverting e847c8b fixes the tplg load, but I want to know why this was added (from PR and commit message is not quite clear).

yes, I reverted it locally and moved fwd to another issue :)
Will wait next week for @btian1 comments.

@btian1

@btian1 can you, please, have a look at this?
As @singalsu suggested here, I would like to revert this e847c8b
