From 8b5d95313b6d30f642e4ed0125891984c446604e Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sat, 31 Jul 2021 10:43:31 +0200 Subject: ASoC: amd: Fix reference to PCM buffer address PCM buffers might be allocated dynamically when the buffer preallocation failed or a larger buffer is requested, and it's not guaranteed that substream->dma_buffer points to the actually used buffer. The driver needs to refer to substream->runtime->dma_addr instead for the buffer address.
