Subject: [PATCH 2/3] ASoC: SOF: hda: Set max DMA segment size
Date: Tue, 15 Feb 2022 14:27:55 +0100 [thread overview]
Message-ID: <20220215132756.31236-3-tiwai@suse.de> (raw)
In-Reply-To: <20220215132756.31236-1-tiwai@suse.de>
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.
Fixes: 2c95b92ecd92 ("ALSA: memalloc: Unify x86 SG-buffer handling (take#3)")
