Subject: [PATCH 03/18] ASoC: SOF: sof-audio: Set up/free DAI/AIF widgets only once
Date: Fri, 27 Jan 2023 14:00:16 +0200 [thread overview]
Message-ID: <20230127120031.10709-4-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>
Calling the sof_widget_setup/free() for the DAI/AIF widgets inside the
snd_soc_dapm_widget_for_each_sink_path() loop will end up setting up or
freeing the widget multiple times if there are multiple paths leaving
the widget. Fix this by moving the widget setup/free for the starting
widget in each path outside the loop.
