Deva Ramasubramanian fa9538adf7 switch: Reset device's drvdata before destroying it 
dev_set_drvdata() sets the device specific driver data at
dev->p->driver_data.  However, dev is destroyed and has it's
context memory freed in device_destroy().  As a result, calling
dev_set_drvdata() causes a fault when accessing dev->p.
