I'm also wondering whether snd_power_change_state() should be moved into RPM callbacks and whether this function does anything practically useful on Tegra at all.
This call is mostly for ALSA core stuff, and not necessarily reflecting the exact device power state. The major role is for controlling / blocking the device accesses at the system suspend/resume, so it's correct to set only in the system suspend/resume callbacks, not in runtime PM.
Thank you for the clarification.
