The ELD notification can be received asynchronously from the graphics side, and this may happen just at the moment the sound driver is processing the suspend or the resume, and it would confuse the whole procedure. Since the ELD and connection states are updated in anyway at the end of the resume, we can skip it when received during PM process.

I applied this particular patch now to for-next branch, as it's basically irrelevant with others.
The rest still needs review.
thanks,
Takashi
