Christophe Jaillet 9376cad207 drm/tegra: dpaux: Fix error handling ...

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().
