From 0dd71a3340b92b503278af4565156f086ccbca3f Mon Sep 17 00:00:00 2001 From: Ranjani Sridharan Date: Thu, 25 Nov 2021 12:15:14 +0200 Subject: [PATCH] ASoC: SOF: pcm: invoke platform hw_free for STOP/SUSPEND triggers snd_sof_pcm_platform_hw_params() will be called when the stream is restarted with a prepare ioctl. This happens in two cases i.e. when a suspended stream is resumed or when a stream is restarted without intermediate call to sof_pcm_hw_free(). Make sure to call snd_sof_pcm_platform_hw_free() in both these cases to keep it balanced.
