[ Upstream commitd03cfde56f] The module core already guarantees that a module can only be unloaded after all other modules using its symbols have been unloaded. As it's already the responsibility of the drivers using firmware_attributes_class to clean up their devices before unloading, the lifetime of the firmware_attributes_class can be bound to the lifetime of the module. This enables the direct usage of firmware_attributes_class from the drivers, without having to go through the lifecycle functions, leading to simplifications for both the subsystem and its users.
