[chirp_devel] Patch for UV5R driver to fix communication on Ubuntu 16.04 with pl2303-based cables (fixes #4165)

[interfect at gmail.com]

All I can say is that I'm unable to reproduce the issue now, on Ubuntu 18.04 which I now use, no matter whether the radio is on or off when I plug it in.

Presumably the person who was bothering me to apply the patch still sees the issue; it might still be broken on 16.04. Maybe something about the serial driver has changed again.
