I'd do explicit "return -EINVAL" here.

And certainly do "return -ENOMEM" explicitly here.


ACK

I've done all amendments requested by Pavel and updated branch
ib-leds-mfd-regulator on linux-leds.git, but in the same time

What do you mean by updated? You cannot update an 'ib' (immutable
branch). Immutable means that it cannot change, by definition.

We have already talked about that. Nobody has pulled so the branch
could have been safely updated.
