4.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sean Young <sean@xxxxxxxx>
commit 413808685dd7c9b54bbc5af79da2eaddd0fc3cb2 upstream.
When the protocol is set via the sysfs protocols attribute, the
decoder is loaded. However, when it is not when a device is first
plugged in or registered.
Fixes: acc1c3c ("[media] media: rc: load decoder modules on-demand")
