mfd: syscon: syscon_node_to_regmap() and device_node refcounting

[Alexey Khoroshilov]

Hello,

Could you please clarify why it is safe to store device_node pointer
in of_syscon_register()? Who is responsible to make sure that 
it is not disappear?

static struct syscon *of_syscon_register(struct device_node *np)
{
...
	syscon->np = np;
}
