From: Ranjani Sridharan Date: Wed, 29 Jan 2020 22:07:18 +0000 (-0600) Subject: ASoC: SOF: Do not reset hw_params for streams that ignored suspend X-Git-Tag: v5.7-rc1~24^2^2~223 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3f06501ea4d2d8add203e66d225274f106cb4029;p=thirdparty%2Flinux.git ASoC: SOF: Do not reset hw_params for streams that ignored suspend Setting the prepared flag to false marks the streams for the hw_params to be reset upon resuming. In the case of the D0i3-compatible streams that ignored suspend to keep the pipeline active in the DSP during suspend, this should not be done.
