    PM / OPP: Update OPP users to put reference · 8a31d9d9
    Viresh Kumar authored
    This patch updates dev_pm_opp_find_freq_*() routines to get a reference
    to the OPPs returned by them.
    
    Also updates the users of dev_pm_opp_find_freq_*() routines to call
    dev_pm_opp_put() after they are done using the OPPs.
    
    As it is guaranteed the that OPPs wouldn't get freed while being used,
    the RCU read side locking present with the users isn't required anymore.
    Drop it as well.
    
    This patch also updates all users of devfreq_recommended_opp() which was
    returning an OPP received from the OPP core.
    
    Note that some of the OPP core routines have gained
    rcu_read_{lock|unlock}() calls, as those still use RCU specific APIs
    within them.
