This patch replaces all remaining uses of cpufreq_cpu_get() with
the __free(cpufreq_cpu_put) annotation.
Motivation:
- Ensures automatic cleanup of policy references when they go out of scope,
reducing the risk of forgetting to call cpufreq_cpu_put() on early return
or error paths.
- Brings the code in line with the latest kernel coding style and best
practices for managing reference-counted objects.
- No functional changes are introduced; behavior remains the same,
but reference counting is now safer and easier to maintain.

This changes different pieces of code maintained by different people
and the changes are not interdependent AFAICS, so better send it as a
series of separate patches.
Thanks!
Thanks for the suggestion.
I agree, splitting it into a series will make the review much clearer.
