There are cases where we fail before we reach soc_new_pcm which would init the workqueue. When we fail we attempt to flush the queue which generates warnings from the workqueue subsystem when we have not inited the queue. Solution is to use a proxy function to get around this issue.

Forgot the change in soc-compress.c?

Thanks for spotting that, I'll send v2, I won't be able to test the compress path as we have no platforms setup for that.
