Subject: [PATCH 04/18] ASoC: SOF: sof-audio: Only process widgets in the connected widget list
Date: Fri, 27 Jan 2023 14:00:17 +0200	[thread overview]
Message-ID: <20230127120031.10709-5-peter.ujfalusi@linux.intel.com> (raw)
In-Reply-To: <20230127120031.10709-1-peter.ujfalusi@linux.intel.com>

From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

When walking the list of the widgets from the source to the sink, we
accidentally also end up preparing/setting up the widgets that are not
in the list of connected DAPM widgets associated with the PCM. Avoid
this by checking if a widget is part of the connected DAPM widget list
during widget prepare, unprepare, setup or free.
