From 1559d14977b694570f010854b8192e6de034bc27 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Wed, 11 Oct 2023 15:02:02 +0200 Subject: gpiolib: provide gpio_device_to_device() There are users in the kernel who need to retrieve the address of the struct device backing the GPIO device. Currently they needlessly poke in the internals of GPIOLIB. Add a dedicated getter function.
