Fwd: [PATCH] lirc_serial: Fix removal of platform device on failed module loads

[Juerg H. <ju...@gm...>]

Add correct removal of platform device in case the loading of the lirc_serial
module fails (for example if the serial port is in use). Otherwise, the
lirc_serial platform device stays around and subsequent attempts to load the
module result in a kernel Oops:
