From 1e1a2ef95b571825ca9c0113f6bef51e9cec98b0 Mon Sep 17 00:00:00 2001 From: Hao Bui Date: Wed, 6 Nov 2024 10:18:20 +0200 Subject: [PATCH] ASoC: da7213: Avoid setting PLL when closing audio stream When audio stream is closing, audio frequency is set to 0 by ALSA but codec driver DA7213 does not handle properly in this case. This patch adds checking of 0Hz frequency to da7213_set_component_sysclk() and avoid unnecessary PLL settings.
