This must address your concerns:
@Rafael: I have attached both patches now for you to apply.

Subject: [PATCH 1/2] cpufreq: tegra: Remove irrelevant comment

Tegra cpufreq driver doesn't use .index field of cpufreq_frequency_table and so
comment mentioning order of .index is irrelevant. Remove it.

Does the .index/.data field even need to be filled in any more?
