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

[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]

[PATCH 12/12] video: mx3fb: use dmaengine_terminate_all() API

[Vinod Koul]

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