So the audio is a Root Complex Integrated Endpoind and there shouldn't be
any problems with it related to PCIe ports power management.
It looks like azx_runtime_suspend() is new in 3.7 and it returns -EAGAIN
to indicate that it actually can't be suspended (if my understanding the
code is correct). However, it shouldn't do that, because that causes
the runtime PM core to repeat the attempts. It rather should implement
a .runtime_idle() callback returning an error code instead.
Those messages are just noise, though.
Thanks,
Rafael
