[PATCH 1/3] of: change superfluous of_fix_tree int return type to void

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

of_fix_tree always returns 0, so propagating its return code and
checking it serves no purpose. Let's just change it to void *.

I considered having it return the first argument, but that could mislead
users to think that the argument is not modified.
