The prepare() ioctl for BE dai link gets called both when the stream is started and when it is resumed from suspend. SOF uses this ioctl to set the hw params again only if the stream has been suspended. When the stream is started, the hw_params ioctl gets called before prepare() and hw_params is set for the BE dai link. So the prepare call does not need to do anything further. When the stream resumes after system suspend, SOF requires that the hw_params be set again for the BE dai. In order to determine which streams should set the hw params during prepare(), an internal flag called "hw_params_upon_resume" is introduced in struct sof_intel_hda_stream. The flag is set for hda streams when the sof device suspends and is cleared after hw_params is set.
