[PATCH 0/2] dmaengine: Use-after-free fix and dummy DMAC

[Vincent Whitchurch <vincent.whitchurch@xxxxxxxx>]

This series has a fix for a use-after-free in the DMA engine framework
and adds a dummy CPU-based "DMA" controller driver which can be used for
testing the DMA engine framework and clients on systems without a real
DMA engine, such as under KVM.
