That's because I didn't have any time yet to backport the fixes for
3.18 and send those to -next. Also, while warnings are annoying,
a warning like that is not really an urgent matter, as gcc should
remove the dead code anyway.

I should be handling fixes next week, after my return from LinuxCon EU,
gstreamer conf, audio mini-summit and media summit. This will be a too
busy week.
