Alrite. will do, I try to trim the headers down to bare minimum, but will take care of it in the formal post. > >> diff --git a/drivers/cpufreq/cpufreq_opp.h b/drivers/cpufreq/cpufreq_opp.h > > Two problems, driver may lie in arch/ as well, though we don't recommend > them, secondly move these in cpufreq.h, don't need a header here for sure. There are none at the moment. ideally, we'd like to discourage folks putting cpufreq drivers in arch/ given the amount of effort you have undertaken in bringing them all here. but I have personally no strong objection to getting rid of the private header and using the generic cpufreq header. Otherwise, I assume you are ok with this approach and will post a formal patch by monday.
