PM / OPP: RCU reclaim
synchronize_rcu() blocks the caller of opp_enable/disbale
for a complete grace period. This blocking duration prevents
any intensive use of the functions. Replace synchronize_rcu()
by call_rcu() which will call our function for freeing the old
opp element.
The duration of opp_enable() and opp_disable() will be no more
dependant of the grace period.
