Yes, and it will be handled correctly, there are guards in the correct places to ensure the input device will not be used before being registered. It is registered at this point since there are several paths that might need the interrupt handler (for example, to handle flash if device is in failed state, or to upload configuration if necessary). -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
