From a09fb3f28a60ba3e928a1fa94b0456780800299d Mon Sep 17 00:00:00 2001 From: Matthias Blankertz Date: Wed, 15 Apr 2020 16:10:16 +0200 Subject: ASoC: rsnd: Fix parent SSI start/stop in multi-SSI mode The parent SSI of a multi-SSI setup must be fully setup, started and stopped since it is also part of the playback/capture setup. So only skip the SSI (as per commit 203cdf51f288 ("ASoC: rsnd: SSI parent cares SWSP bit") and commit 597b046f0d99 ("ASoC: rsnd: control SSICR::EN correctly")) if the SSI is parent outside of a multi-SSI setup.
