From 7547dbd3b198f309aaff54e3528898a8a196faff Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 28 Aug 2020 14:05:07 +0300 Subject: dmaengine: Mark dma_request_slave_channel() deprecated New drivers should use dma_request_chan() instead dma_request_slave_channel() dma_request_slave_channel() is a simple wrapper for dma_request_chan() eating up the error code for channel request failure and makes deferred probing impossible. Move the dma_request_slave_channel() into the header as inline function, mark it as deprecated.
