It has a lot to do with pinctrl I think, so I get confused by this commit message. > extern int pinctrl_gpio_request(unsigned gpio); > +extern int pinctrl_mux_gpio_request_enable(unsigned gpio); What's wrong with just using the existing call pinctrl_gpio_request() right above your new one? It's not like we're reference counting or something, it's just a callback. Sprinkle some comments to show what's going on. If you for some reason need a new call for this specific use case, it needs to be named after the use case, like pinctrl_gpio_request_for_irq() so it is obvious what the function is doing.
