+The probe() entry is called in task context, with the bus's rwsem locked

+container_of() to convert "dev" to a bus-specific type, both in probe()
+and other routines.  That type often provides device resource data, such
+as pci_dev.resource[] or platform_device.resources, which is used in
+addition to dev->platform_data to initialize the driver.
+
+This callback holds the driver-specific logic to bind the driver to a
+given device.  That includes verifying that the device is present, that
+it's a version the driver can handle, that driver data structures can
+be allocated and initialized, and that any hardware can be initialized.
+Drivers often store a pointer to their state with dev_set_drvdata().
+When the driver has successfully bound itself to that device, then probe()
+returns zero and the driver model code will finish its part of binding
+the driver to that device.

+the driver did not bind to this device, in which case it should have
