From 5dc302d00807b8916992dd25a7a22b78d07dcd03 Mon Sep 17 00:00:00 2001 From: Pei Xiao Date: Fri, 6 Jun 2025 17:18:21 +0800 Subject: [PATCH 1/2] ASOC: rockchip: fix capture stream handling in rockchip_sai_xfer_stop Correcting the capture stream handling which was incorrectly setting playback=true for capture streams. The original code mistakenly set playback=true for capture streams, causing incorrect behavior.

Moreover, it is no longer necessary to unprepare and disable the clocks explicitly.
