Surprise! I don't like this.

I think it is better to first go over the call sites and make them
all handle negative return numbers rather than pushing the
obscure __interface.

I know from patch 0 that you think it's too much to change these
127 call sites but I don't think so, and I'm happy to merge one
big patch changing all the 20 users in drivers/gpio.

Likewise with the 11 consumers in drivers/pinctrl.

It's just a a few archs+subsystems and it's just plain work.

So do that first.

Yours,
Linus Walleij
