It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

Bit of nit picking, but any reason, why there are multiple spaces, before "reg" here?

  			return info.id;
node = of_get_parent(ep);
