cpufreq: schedutil: make kobj_type structure constant

t-8ch · rafaeljw · commit 70ba26cbe026 · 2023-02-23T19:57:29.000+01:00
Since commit ee6d3dd ("driver core: make kobj_type constant.") the driver core allows the usage of const struct kobj_type. Take advantage of this to constify the structure definition to prevent modification at runtime.
