From 42bc62c9f1d3d4880bdc27acb5ab4784209bb0b0 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 28 Jul 2021 13:23:51 +0200 Subject: ASoC: xilinx: 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.
