Subject: [PATCH] rc: raw decoder for keymap protocol is not loaded on register
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")
