[PATCH] [media] rc: raw decoder for keymap protocol is not loaded on register

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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")
