Given the header removal in patch 4, I assume these all need to go together
via mfd.

Fingers crossed it's just docs changes for v11.
So on to the details of how to merge this...
For the DMAEngine maintainers:

Rusty, Tejun. I kept your sign of an ack for the first patch. Could
you quickly verify that's fine?
Thanks,

The current hyper-optimized functions are overkill if you simply want
to allocate an id for a device. Create versions which use an internal
lock.
Thanks to Tejun for feedback.

Some messing with error codes to return 0 on out id's and match
