From bd588d52562ac5c2d7dd43cf4420d112d9e9c2d5 Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Mon, 25 Mar 2024 20:33:36 +0100 Subject: [PATCH] clk: rockchip: fix error for unknown clocks commit 12fd64babaca4dc09d072f63eda76ba44119816a upstream. There is a clk == NULL check after the switch to check for unsupported clk types. Since clk is re-assigned in a loop, this check is useless right now for anything but the first round. Let's fix this up by assigning clk = NULL in the loop before the switch statement.
