Hi Taniya,

Sorry that I haven't been reviewing it much from last few iterations as I was
letting others get this into a better shape. Thanks for your efforts..

Now that the code is much more simplified, I am not sure if you need this
per-cpu structure at all. The only place where you are using it is in
qcom_cpufreq_hw_cpu_init() and probe(). Why not merge qcom_cpu_resources_init()
completely into qcom_cpufreq_hw_cpu_init() and get rid of this structure
entirely ?
