From 4f8e0e83366e1e6489c87e5560042ea07704cacc Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 11 Jan 2023 12:30:07 +0100 Subject: [PATCH] driver core: make struct device_type.uevent() take a const * The uevent() 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.
