There is a discussion here:
https://lkml.org/lkml/2020/5/20/1100

There are many use cases that suppose pm_runtime_get_sync() will always
increment the usage counter and do not check its return value. So I don't
think we should adjust this function directly.

As for this API, Dan suggested a replacement (wrapper) for later developers.
I think this is the best solution.
