From: Sylwester Nawrocki Date: Thu, 7 Feb 2019 17:00:09 +0000 (+0100) Subject: ASoC: dmaengine: Improve of_node test in dmaengine_pcm_request_chan_of() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=51256d348c9af1bf544a4432abc1d5f2fd3ef34b;p=openwrt%2Fstaging%2Fblogic.git 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.
