Subject: [PATCH] ASoC: fsl_sai: remove reset code from dai_probe
Date: Tue, 16 Mar 2021 17:27:06 +0800	[thread overview]
Message-ID: <1615886826-30844-1-git-send-email-shengjiu.wang@nxp.com> (raw)

From: Viorel Suman <viorel.suman@nxp.com>

SAI software reset is done in runtime resume,
there is no need to do it in fsl_sai_dai_probe.
