There are lots of users in kernel with such sequences, ex:

Sorry not a fan of this:) I think PM core should do this :D
Yes, I would prefer that too, There might be a reason why its not done
in the pm core, I will catchup with Ulf next week and see if we can add
checks to return -ENOSUPPORT or something more sensible error code to
users.
Thanks,

I guess you are trying to solve the case where PM can be disabled for a
device and pm_runtime_get_sync() returns error right?
That would be quite a common sequence in most frameworks..
Thanks
