After a recent update of xf86-input-evdev and xorg-server, I noticed
that X11 applications did not receive keypresses from the FireDTV
infrared remote control anymore. Instead, the Xorg log featured lots of
"FireDTV remote control: dropping event due to full queue!"
exclamations. The Linux console did not have an issue with the
FireDTV's RC though.
The fix is to insert EV_SYN events after the key-down/-up events.
