Marek Szyprowski 474809a28e dmaengine: Fix return value for dma_request_chan() in case of failure ... Commit 71723a96b8 ("dmaengine: Create symlinks between DMA channels and slaves") changed the dma_request_chan() function flow in such a way that it always returns EPROBE_DEFER in case of channels that cannot be found. This break the operation of the devices which have optional DMA channels as it puts their drivers in endless deferred probe loop. Fix this by propagating the proper error value.
