From: Takashi Iwai Date: Tue, 15 Feb 2022 13:27:55 +0000 (+0100) Subject: ASoC: SOF: hda: Set max DMA segment size X-Git-Tag: baikal/aarch64/sdk6.1~4639^2~1 X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=80c6c1b96faa166ed700847cc8ff7322db3ef9ad;p=kernel.git ASoC: SOF: hda: 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.
