Subject[PATCH v2 2/2] driver core: Make bus notifiers in right order in really_probe()
Date
If a driver cannot be bound to a device, the correct bus notifier order
should be:

- BUS_NOTIFY_BIND_DRIVER: driver is about to be bound
- BUS_NOTIFY_DRIVER_NOT_BOUND: driver failed to be bound

or no notifier if the failure happens before the actual binding.

The really_probe() notifies a BUS_NOTIFY_DRIVER_NOT_BOUND event without
a BUS_NOTIFY_BIND_DRIVER if .dma_configure() returns failure. This
change makes the notifiers in order.
