From 0e17e50b993043cf3e21512a43ca63d176b46459 Mon Sep 17 00:00:00 2001 From: Shuming Fan Date: Fri, 4 Sep 2026 15:58:26 +0800 Subject: [PATCH] ASoC: rt721: fix uninitialized stream_config->type The stream_config variable was not initialized before being passed to sdw_stream_add_slave(). This may cause unexpected behavior when configuring the SoundWire stream.
