looks like a bug in <linux/pinctrl/consumer.h>. Something along the
lines of below should be enough:

Linus, do you want me to send this as a proper patch? It's pretty clear
that currently we can have build regressions with these helpers. Was it
a conscious choice to not provide stubs or just a slip?

I don't think so, that include file looks pretty solid.

I think the actual problem is that dwc3-st.c doesn't
#include <linux/pinctrl/consumer.h> even if it is using the
functions from it.

Oh, I missed that there was already a stub further down the
file. Indeed, we need to add a patch to dwc3-st.c.

Sorry for the noise.
