Subject: [PATCH] drm: xlnx: Use dma_request_chan for DMA channel request
Date: Fri, 23 Oct 2020 12:46:02 +0300 [thread overview]
Message-ID: <20201023094602.5630-1-peter.ujfalusi@ti.com> (raw)
There is no need to use the of_dma_request_slave_channel() directly as
dma_request_chan() is going to try to get the channel via OF as well.
