Subject: media: lirc: drop trailing space from scancode transmit
From: Sean Young <sean@xxxxxxxx>
commit c8a489f820179fb12251e262b50303c29de991ac upstream.
When transmitting, infrared drivers expect an odd number of samples; iow
without a trailing space. No problems have been observed so far, so
this is just belt and braces.
