+Subject: [PATCH] clk: bcm: rpi: Make sure pllb_arm is removed
+
+The pllb_arm clock was created at probe time, but was never removed if
+something went wrong later in probe, or if the driver was ever removed from
+the system.
+
+Now that we are using clk_hw_register, we can just use its managed variant
+to take care of that for us.
