From 8be4da29cf5b8ec65e974c36e7ae4d90b381ac5e Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sat, 25 Oct 2014 17:42:01 +0200 Subject: 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.
