From c22a8086b384025ab97ce07465420a219697d3f2 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 15 Feb 2022 14:27:56 +0100 Subject: [PATCH] ASoC: intel: skylake: Set max DMA segment size The recent code refactoring to use the standard DMA helper requires the max DMA segment size setup for SG list management. Without it, the kernel may spew warnings when a large buffer is allocated. This patch sets up dma_set_max_seg_size() for avoiding spurious warnings.
