+Subject: [PATCH] clk: bcm: rpi: Make sure the clkdev lookup is removed
+
+The clkdev lookup created for the cpufreq device is never removed if
+there's an issue later in probe or at module removal time.
+
+Let's convert to the managed variant of the clk_hw_register_clkdev function
+to make sure it happens.
