I think the prototype of this function should be changed to:
static int __init exynos_cpufreq_init(struct platform_device *pdev)
to avoid compilation warnings.

Hi Tomasz Figa,
One more thing. :-)
It makes section mismatch warning. Also, module_platform_driver()
is used. Then, '__init' annotation can be removed in order to fix
the section mismatch warning.
static int exynos_cpufreq_init(struct platform_device *pdev)
Thank you.
