The other patch on which you commented about unnecessary read locks being taken:
[PATCH 181/228] cpufreq: move freq change notifications to cpufreq
That calls these notifiers, for all platforms except the ones that have set CPUFREQ_ASYNC_NOTIFICATION, before and after calling ->target_index()..
And so functionally the code is supposed to be the same.. Unless I have done some stupid mistake..
