1. Please use -M with move patches...

2. susbsytem is dmaengine

3. Why move..? These things are internal to the driver and I dont think
it is wise for clients to use everything here... If the client needs to
know defer probe, it should request a channel and check the status
returned for EPROBE_DEFER

Thanks
