Should check this + as Andy pointed out in earlier review this
call will return an error if fwnode not present anyway so can skip
earlier check.
see fwnode_call_int_op() definition.
Otherwise, Andy has given some detailed review. I wouldn't suggest
applying the style cleanup to existing code but he's entirely
correct that we can make the stuff being touched anyway easier
to read.
The more functional stuff maybe needs to be looked at in other
drivers though.
