If the target device has any suppliers, as reflected by device links to them, __pm_runtime_set_status() does not take them into account, which is not consistent with the other parts of the PM-runtime framework and may lead to programming mistakes. Modify __pm_runtime_set_status() to take suppliers into account by activating them upfront if the new status is RPM_ACTIVE and deactivating them on exit if the new status is RPM_SUSPENDED. If the activation of one of the suppliers fails, the new status will be RPM_SUSPENDED and the (remaining) suppliers will be deactivated on exit (the child count of the device's parent will be dropped too then). Of course, adding device links locking to __pm_runtime_set_status() means that it cannot be run fron interrupt context, so make it use spin_lock_irq() and spin_unlock_irq() instead of spin_lock_irqsave() and spin_unlock_irqrestore(), respectively.
