Sascha Hauer	8267f16e8b	dma: imx-dma: fix signedness bug ... mxdmac->channel was unsigned, so check (imxdmac->channel < 0) for failed imx_dma_request_by_prio() made no sence. Explicitly check signed values. Also, fix uninitialzed use of ret.

Sascha Hauer	1f1846c6ce	dmaengine: Add Freescale i.MX1/21/27 DMA driver ... This driver is currently implemented as a user to the old i.MX DMA API. This allows us to convert each user of the old API to the dmaengine API one by one. Once this is done the old DMA driver can be merged into the i.MX dmaengine driver.
