From 550fac229e469b75ab4609b617146314786c62b3 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 13 Mar 2023 19:29:11 +0100 Subject: [PATCH] crypto: hisilicon/qm - make struct bus_type * const In the function, qm_get_qos_value(), a struct bus_type * is used, but it really should be a const pointer as it is not modified anywhere in the function, and the driver core function it is used in expects a constant pointer.
