[issue34886] subprocess.run throws exception when input and stdin are passed as kwargs

[Alessandro]

Alessandro <aecantini at gmail.com> added the comment:

subprocess.run('ls', input=b'', stdin=None) # this is ok

kwargs = {'input': b'', 'stdin': None}
subprocess.run('ls', **kwargs) # this throws exception

The two calls should have the same behaviour, but one throws exception and the other doesn't. I think the exception shouldn't be thrown, because stdin is None.
