Sergey Shtylyov ecfe9a015d pinctrl: core: handle radix_tree_insert() errors in pinctrl_register_one_pin() 
pinctrl_register_one_pin() doesn't check the result of radix_tree_insert()
despite they both may return a negative error code.  Linus Walleij said he
has copied the radix tree code from kernel/irq/ where the functions calling
radix_tree_insert() are *void* themselves; I think it makes more sense to
propagate the errors from radix_tree_insert() upstream if we can do that...
