From 827f3164aaa579eee6fd50c6654861d54f282a11 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 28 Jul 2021 13:23:52 +0200 Subject: ASoC: uniphier: Fix reference to PCM buffer address Along with the transition to the managed PCM buffers, the driver now accepts the dynamically allocated buffer, while it still kept the reference to the old preallocated buffer address. This patch corrects to the right reference via runtime->dma_addr. (Although this might have been already buggy before the cleanup with the managed buffer, let's put Fixes tag to point that; it's a corner case, after all.)
