From 199a3754f2736808d7bfa4c962eaf89e1d17e462 Mon Sep 17 00:00:00 2001 From: Ranjani Sridharan Date: Mon, 27 Sep 2021 15:05:07 +0300 Subject: [PATCH] ASoC: SOF: control: Add access field in struct snd_sof_control Add a new field to save the access setting for all controls in struct snd_sof_control. This will be used to ensure that only widgets belonging to static pipelines have volatile controls.
