That's the plan, I'd leave it up to Rafael to decide if further cleanup patches should be included in 3.9 merge window or skip to the following one... I understand that we are starting to be late on the -rc and I also prefer to focus on fixup.

The deadline for 3.9 merge window patches is about 2 days before 3.8-rc7 (assuming that there will be -rc7) and by that time they need to be in linux-next. Whatever doesn't make it will have to go after 3.9-rc1 or be postponed until the 3.10 merge window. Thanks, Rafael

For everybody else, i have patched above in a different patchset. -- To unsubscribe from this list: send the line "unsubscribe linux-pm" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Drop unused arguments from dbs_timer_init and clean dbs_timer_exit and cpufreq_governor_dbs to remove non necessary special cases.
