[PATCH v3 07/14] net: smc911x: remove the dmaengine compat need

From: Robert Jarzmik
Date: Sun Jun 17 2018 - 13:05:57 EST


As the pxa architecture switched towards the dmaengine slave map, the
old compatibility mechanism to acquire the dma requestor line number and
priority are not needed anymore.

This patch simplifies the dma resource acquisition, using the more
generic function dma_request_slave_channel().

Since v2: converted to NULL filter function and NULL dma parameter call
