False positive E1111 (assignment-from-no-return) for sys.stdin.read()

[jeffwidman]

False positive E1111 (assignment-from-no-return) for sys.stdin.read().

Code:

if __name__ == "__main__":
    import sys
    data = sys.stdin.read()

The final line here throws E1111:

E: Assigning to function call which doesn't return (assignment-from-no-return)

However, sys.stdin.read() does return, so this is a false positive.

Pylint version: 2.1.1

Weirdly, this is only thrown on python 3.5 and 3.6, not on 2.7 or 3.4.
