Whenever we are changing frequency of a cpu, we are calling PRECHANGE and POSTCHANGE notifiers. They must be serialized. i.e. PRECHANGE or POSTCHANGE shouldn't be called twice contiguously. This can happen due to bugs in users of __cpufreq_driver_target() or actual cpufreq drivers who are sending these notifiers. This patch adds some protection against this. Now, we keep track of the last transaction and see if something went wrong. Signed-off-by: NViresh Kumar <viresh.kumar@linaro.org> Signed-off-by: NRafael J. Wysocki <rafael.j.wysocki@intel.com>

PRECHANGE and POSTCHANGE notifiers must be called in groups, i.e either both should be called or both shouldn't be. In case we have started PRECHANGE notifier and found an error, we must call POSTCHANGE notifier with freqs.new = freqs.old to guarantee that sequence of calling notifiers is complete.

In case we have started PRECHANGE notifier and found an error, we must call POSTCHANGE notifier with freqs.new = freqs.old to guarantee that sequence of calling notifiers is complete. Omap driver was taking care of it well, but wasn't restoring freqs.new to freqs.old in some cases. I wasn't required to add code for it as moving PRECHANGE notifier down was a better option, so that we call it just before starting frequency transition.
