ASoC: dapm: Mark endpoints instead of IO widgets dirty during suspend/resume
The state of endpoint widgets is affected by that card's power state. Endpoint widgets that do no have the ignore_suspend flag set will be considered inactive during suspend. So they have to be re-checked and marked dirty after the card's power state changes. Currently the input and output widgets are marked dirty instead, this works most of the time since typically a path from one endpoint to another will go via a input or output widget. But marking the endpoints dirty is technically more correct and will also work for odd corner cases. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
