From 69df024ebbf8b1d4d8f0808b5700688fed9e45e9 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 13 Mar 2023 19:18:37 +0100 Subject: [PATCH] driver core: class: make class_for_each_device() options const class_for_each_device() does not modify the struct class or the struct device passed into it, so mark them as const * to enforce that.
