From db2292b01b799e926abfdbd6fafa1f27f0d0e457 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 19 Dec 2023 15:07:23 +0100 Subject: [PATCH] PM: clk: make pm_clk_add_notifier() take a const pointer The driver core wants to work with const struct bus_type, so there's no reason that pm_clk_add_notifier() should not also do the same thing, considering that it just passes the pointer off to the driver core which is expecting a const *.
