As it devm_pm_runtime_enable() can fail due to memory allocations, it
is best to handle the error.

I'm worried now only about missing a commit message in one patch and
(with less severity) the v2 of this one which appears not to be
necessary (i.e. v1 is fully okay). If you consider the commit message
absence is okay, feel free to apply v2, otherwise with that addressed
v3 can go in my opinion.

Btw, TIL that your v1 was fully correct as there is no use of the type
definitions. In case you are going to send v3, you can use v1 of this
patch if you want, this version is also okay (as we have some more
like this pattern, which probably needs to be amended in the future).

Please fix-up and submit a v4 with Andy's R-bs.
