Subject: [PATCH 3/5] [media] staging: lirc_parallel: remove

The lirc_parallel driver was merged in 2010 and noone has attempted
to do the work necessary to get it out of staging (i.e. port it to
rc-core). I have not been able to find one of these devices, and
a machine with a parallel port is pretty rare too.
