Speak of left over stuff, it's weird that I didn't notice this before
but gcc complains about an unitialized variable in
imon_incoming_packet().

drivers/staging/lirc/lirc_imon.c: In function ‘imon_incoming_packet’:
drivers/staging/lirc/lirc_imon.c:661: warning: ‘chunk_num’ may be used
	uninitialized in this function

I don't know how to fix that, but it looks important.
