More power supply drivers depends on vbus events and without it they not working. Power supply drivers using usb_register_notifier, so to deliver events it is needed to call atomic_notifier_call_chain. So without atomic notifier power supply driver isp1704 not retrieving vbus status and reporting bogus values to userspace and also to board platform data functions. Without proper data charger drivers trying to charge battery also when charger is disconnected or do not start charging when wallcharger connects. Atomic notifier in musb driver was used before v3.5 and was replaced with omap mailbox. This patch adding atomic_notifier_call_chain call from function omap_musb_set_mailbox.
