## Description

In the Linux kernel, the following vulnerability has been resolved:  cpufreq: davinci: Fix clk use after free  The remove function first frees the clks and only then calls cpufreq_unregister_driver(). If one of the cpufreq callbacks is called just before cpufreq_unregister_driver() is run, the freed clks might be used.
