From a28e1c0505a09c3a2d81fed1c8453ac2d8d02b3a Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 13 Mar 2020 09:15:22 +0100 Subject: [PATCH] gpio: Move devres calls to devres file These two devres functions devm_gpiochip_[add|remove]() were in the wrong file. They should be in gpiolib-devres.c not gpiolib.c.
