From e957204e732bc2916a241dc61dd7dd14e9a98350 Mon Sep 17 00:00:00 2001 From: Shengjiu Wang Date: Fri, 27 Sep 2019 09:46:11 +0800 Subject: ASoC: pcm_dmaengine: Extract snd_dmaengine_pcm_refine_runtime_hwparams When set the runtime hardware parameters, we may need to query the capability of DMA to complete the parameters. This patch is to Extract this operation from dmaengine_pcm_set_runtime_hwparams function to a separate function snd_dmaengine_pcm_refine_runtime_hwparams, that other components which need this feature can call this function.
