I see your point but I think we should cross that bridge when we get there. Shouldn't be too hard, we already have an entry point: gpiod_request_user() where we could set an additional flag marking the descriptor as requested by user-space in which case, when we get to the relevant pinctrl code, it could check this and refuse based on whether the descriptor was requested from within the kernel or from outside.
