pinctrl: rza1: Handle devm_kasprintf() failure cases

Browse source

[ Upstream commit db221412cd ]

devm_kasprintf() may return NULL on failure of internal allocation
thus the assignments are not safe if not checked. On error
rza1_pinctrl_register() respectively rza1_parse_gpiochip() return
negative values so -ENOMEM in the (unlikely) failure case of
devm_kasprintf() should be fine here.
