4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sean Young <s...@mess.org>

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")
