From 5952280750f854efc89c6dab6d68a028cb47f475 Mon Sep 17 00:00:00 2001 From: Ondrej Jirman Date: Sat, 27 Aug 2022 20:48:32 +0200 Subject: [PATCH 388/389] ASoC: codec: rt5640: Resolve failure to set DMIC clock after playback rt5640_set_dai_sysclk is called with freq == 0 when playback stops. This causes DMIC setup code to fail. I2S interface doesn't need to be active for codec to work, so don't clear rt5640->sysclk after rt5640_set_dai_sysclk is called with freq == 0.
