It appears that the driver misses the support of dmaengine_terminate_sync(). Since many of callers expects this behaviour implement the new device_synchronize() callback to allow proper synchronization when stopping a channel.
This adds missing support for an optional call, but I am not aware of any reports of breakage due to missing this patch. Do you want to carry this for stable?
I guess that using the word "expect" in the commit log suggested to me that this wasn't optional.
I'll drop it, thanks!
