PM / Wakeup: Remove useless synchronize_rcu() call
wakeup_source_add() adds an item into wakeup_sources list. There is no need to call synchronize_rcu() at this point. Its only needed in wakeup_source_remove() Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
