Good!

I might test, but I'm currently very busy with some other stuff,
so I won't likely have time for it anytime soon.

Deferring request_module to a work_queue is a common procedure we
do at v4l drivers. It helps to initialize faster, and prevents some
dependency issues, as the decoders depend on rc_core to be initialized,
in order to load.

Well, if you press an RC key while the needed decoded is not loaded,
that key will be lost. No other problems should happen.
