[PATCH 00/12] dmaengine: remove users of device_control

[Vinod Koul]

The recent discussion [1] on the API have resulted in moving away from
device_control ioctl method to proper channel APIs.
There are still few users on the device_control which should use the wrappers
existing rather than access device_control.
This will aid us in deprecating and removing device_control, possibly after
the merge window.

These can be merged thru respective subsystem tree or dmaengine tree. Either
way please just let me know.

Feng's kbuild has tested these as well [2]

The drivers should use dmaengine_terminate_all() API instead of
accessing the device_control which will be deprecated soon

I already send a similar patch a while ago. It is on it's way into 3.18.

I will drop this one then

I did grep the linux-next when I started on this and found no reductions
from what I had in dmaengine-next

It's ff495d3a8ea4d (ASoC: txx9: Don't opencode DMAengine API calls) from
August which is in Linus' tree now.

Applying to dmaengine-next with acks recived, dropping the ones which are
applied by respective folks
