From 20f7a0dba9075fb0e3d645495bc24d7025b58de1 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Mon, 26 Sep 2022 18:25:18 +0800 Subject: [PATCH] clk: mediatek: fix unregister function in mtk_clk_register_dividers cleanup When the cleanup paths for the various clk register APIs in the MediaTek clk library were added, the one in the dividers type used the wrong type of unregister function. This would result in incorrect dereferencing of the clk pointer and freeing of invalid pointers. Fix this by switching to the correct type of clk unregistration call.
