From a9b12f8b4e3309c4c25d39e7ab818943b9c48c1c Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 11 Jan 2023 12:30:08 +0100 Subject: driver core: make struct device_type.devnode() take a const * The devnode() callback in struct device_type should not be modifying the device that is passed into it, so mark it as a const * and propagate the function signature changes out into all relevant subsystems that use this callback.
