From c9a9f18d3ad8acb9f9d6b52b5e1922a70b48dc35 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 13 Mar 2023 19:29:12 +0100 Subject: [PATCH] drm/i915/huc: use const struct bus_type pointers The struct bus_type pointers in the functions intel_huc_register_gsc_notifier() and intel_huc_unregister_gsc_notifier() should be a const pointer, as the structure is not modified anywhere in the functions, and the pointer they are passed will be a const * in the near future.
