commit c8f79808cd8eb5bc8d14de129bd6d586d3fce0aa upstream.
The card power state change via snd_power_change_state() at the system suspend/resume seems dropped mistakenly during the PM code rewrite. The card power state doesn't play much role nowadays but it's still referred in a few places such as the HDMI codec driver.
This patch restores them, but in a more appropriate place now in the prepare and complete callbacks.
