From 2a81ada32f0e584fc0c943e0d3a8c9f4fae411d6 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 11 Jan 2023 12:30:17 +0100 Subject: driver core: make struct bus_type.uevent() take a const * The uevent() callback in struct bus_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.
