"assignment-from-none" false positive on generator

[CrepeGoat]

Steps to reproduce

1. Create a new .py file with the following contents:

def paused_iter(iterable):
    """Iterate an iterable, yielding the previous item using `i.send(True)`."""
    iterator = iter(iterable)

    while True:
        try:
            value = next(iterator)
        except StopIteration:
            return

        # Continue to yield the same item until `next(i)` or `i.send(False)`
        while (yield value):
            pass


ITERATOR = paused_iter(range(3))

2. Run pylint on this file.

Current behavior

Pylint reports the following error:

/path/to/file.py:15:0: E1128: Assigning result of a function call, where the function returns None (assignment-from-none)

Expected behavior

The above error does not apply to the above valid code since the function that "returns None" is a generator. Thus, I expect that no such error should be reported.
