-Subject: [PATCH v9 5/7] clk: rockchip: fix error for unknown clocks
-Date: Mon, 25 Mar 2024 20:33:36 +0100	[thread overview]

-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.
