Date: Thu, 07 Feb 2019 18:00:09 +0100 From: Sylwester Nawrocki <s.nawrocki@...sung.com> To: broonie@...nel.org Cc: lgirdwood@...il.com, krzk@...nel.org, sbkim73@...sung.com, m.szyprowski@...sung.com, b.zolnierkie@...sung.com, alsa-devel@...a-project.org, linux-kernel@...r.kernel.org, linux-samsung-soc@...r.kernel.org, Sylwester Nawrocki <s.nawrocki@...sung.com> Subject: [PATCH 01/22] ASoC: dmaengine: Improve of_node test in dmaengine_pcm_request_chan_of() Currently when of_node of the "PCM" device is null dmaengine_pcm_request_chan_of() function will bail out, including cases when custom DMA device is intended to be used. To have the channels properly requested when custom DMA device is provided extend the of_node test to also consider dma_dev->of_node.
