From 5fdb91695f0eb7e37a4913b4c5bf9c9db0943c7d Mon Sep 17 00:00:00 2001 From: "Yoon (Seungyoon) Lee" Date: Tue, 30 Apr 2019 15:28:54 -0500 Subject: [PATCH] ASoC: cs47l35: use dsp running flag for dsp status instead of checking DSP memory address for DSP core status, check the flag from wm_adsp to determine algorithm status.
