Acked-by: Arnd Bergmann <arnd@...db.de>
Cc: stable@...r.kernel.org
Fixes: 2ceeca0499d7 ("[media] rc: split nec protocol into its three variants")
Fixes: d3c501d1938c ("V4L/DVB: dib0700: Fix RC protocol logic to properly handle NEC/NECx and RC-5")


The warning is gone for me too, so this obsoletes both
https://patchwork.linuxtv.org/patch/37494/ and
https://patchwork.kernel.org/patch/9380747/

Can we get this patch merged into v4.9 soonish? The warning
is currently disabled, but I'd like to make sure it gets turned
on again by default, and we should fix all the actual bugs in
the process.
