The i.MX SDMA driver leaks memory when a currently running descriptor is aborted. Calling vchan_terminate_vdesc() on it to fix this revealed that the virt-dma support calls the desc_free with the spin_lock held. This doesn't work for the SDMA driver because it calls dma_free_coherent in its desc_free hook. This series aims to fix that up.
