Because I need to manipulate name by adding the index to it during run time and use it as miscdev's name 

	snprintf(rsmu->name, sizeof(rsmu->name), "rsmu%d", rsmu->index);
	rsmu->miscdev.name = rsmu->name;

For things like dev_err(rsmu->dev, "Undefined RSMU IOCTL");

Will do for the next patch

name is based on this index in the first place
