No, I'm afraid not. Generally only bug fixes are backported to the stable trees, but we make an exception for simple patches adding new device ids to existing drivers. That's what 4dcf9ddc9ad5 ("USB: serial: pl2303: add new PID to support PL2303TB") did, and that's why it got backported. This patch, in contrast, adds support for a new protocol used by a class of devices which were not supported before, and therefore does not meet the stable-kernel criteria for backports. Johan
