Not sure what "usual" means, but if the user has a device in question,
then it's struct fwnode_handle (7 pointers + u8, unpacked) per each
modprobe. Taking into account that there are usually not so many of
the same LED devices in the system  and the user rarely does
rmmod/insmod cycle, I can say a few dozens of bytes.
