4.14-stable review patch. If anyone has any objections, please let me know.
From: Peter Ujfalusi peter.ujfalusi@ti.com
[ Upstream commit de92436ac40ffe9933230aa503e24dbb5ede9201 ]
To avoid race with vchan_complete, use the race free way to terminate running transfer.
Implement the device_synchronize callback to make sure that the terminated descriptor is freed.

This patch is causing a build error on arm and arm64 per i.e. https://kernelci.org/build/id/5aac017e59b5141cb1b3a4d5/
Builds are also failing for arm/arm64 on 4.15 and this patch seems to be a problem there as well, but I have not verified it yet.
I think we are missing commit 1c7f072d94e8. Pls cherrypick that as well

dmaengine: virt-dma: Support for race free transfer terminationThis adds vchan_terminate_vdesc API..
Thanks, that helped. I've now added this and send out a -rc2 for this kernel.
