Enabling/disabling a widget (snd_soc_dapm_enable_pin) then connecting it to a path works as expected, ie. when the widget is disabled the path doesn't power up and it does when the widget is enabled. However once in a path enabling the widget does not cause anything to power up, dapm_widget_set_power will return the current power state of the widget as 1, meaning we never check peer power states. This patch updates dapm_always_on_check_power to return w->connected such that it is effected by snd_soc_dapm_enable_pin and the like.
