From 2bd5c63978b771462da10d8771f56a1e656501d9 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 13 Mar 2023 19:18:43 +0100 Subject: driver core: device: make device_create*() take a const struct class * The functions device_create() and device_create_with_groups() do not modify the struct class passed into it, so enforce this by changing the function parameters to be struct const class.
