opp_get_notifier() needs to be under rcu_lock?
Quoted 10 lines
Hi,
It looks like
find_device_opp()(called fromopp_get_notifier()) needs to be under RCU read lock, but this doesn't seem to be happening indrivers/devfreq/devfreq.c. Doesn't this run the risk of referencing a freed variable?Thanks,

Yes, that's an issue requiring updates.
Thank you for pointing out.
Cheers,
MyungJoo
