Michael Hanselmann e72dbeff67 USB: serial: ch341: add basis for quirk detection ... commit c404bf4aa9236cb4d1068e499ae42acf48a6ff97 upstream. A subset of CH341 devices does not support all features, namely the prescaler is limited to a reduced precision and there is no support for sending a RS232 break condition. This patch adds a detection function which will be extended to set quirk flags as they're implemented. The author's affected device has an imprint of "340" on the turquoise-colored plug, but not all such devices appear to be affected.
