Documentation of QAudioInput: value 'bufferSize' is in bytes, not milliseconds

The documentation of QAudioInput::bufferSize() and QAudioInput::setBufferSize() says: unit is milliseconds. This is wrong, must be bytes.
(That bytes, not milliseconds, is correct can be seen in QAudioInputPrivate::open(), qaudioinput_win32_p.cpp; and in QAudioOUTPUT it is also in bytes).
