These are warnings about the pinctrl-npcm7xx driver that became (more
easily) visible under CONFIG_COMPILE_TEST through my patch.

These two:

[PATCH v5 4/9] dt-bindings: pinctrl: Add Nuvoton WPCM450
[PATCH v5 5/9] pinctrl: nuvoton: Add driver for WPCM450

and the rest can go through Joel Stanley's BMC tree, I think.
