Looks like Greg picked up this patch[1] as commit b8fe128dad8f
("arch_topology: Adjust initial CPU capacities with current freq") from
the list. Not sure it's correct though and I haven't looked in any more
detail. At least, not calling clk_put() unless it is a valid pointer
will work to quiet this warning.
