This is only possible if serdev support is compiled in as the code hooks into TTY. Otherwise PM will silently break as the corresponding platform devices would no longer be registered and as the tty class device is also gone and hciattach (btattach) will also fail.

Please properly line-wrap your changelog comments like your editor is
asking you to do...
