4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Christophe Jaillet <christophe.jaillet@xxxxxxxxxx> commit 9376cad2073d2c122864754ea5f80025c8507b0b upstream. The devm_pinctrl_register() function returns an error pointer or a valid handle. So checking for NULL here is pointless and can never trigger. Check the returned value with IS_ERR instead and propagate this value as done in the other functions which call devm_pinctrl_register().
