From 8a353d7bafddb447fae136ca68899a6ba6187be6 Mon Sep 17 00:00:00 2001 From: Kai Vehmanen Date: Tue, 16 Feb 2021 19:22:51 +0200 Subject: [PATCH] ASoC: soc-pcm: fix hw param limits calculation for multi-DAI In case DPCM runtime has multiple CPU DAIs, dpcm_init_runtime_hw() is called multiple times, once for each CPU DAI. This will lead to ignoring hw limits of all but the last DAI. Fix this by moving soc_pcm_hw_init() up by one level to dpcm_init_runtime_hw().
