The firmware load control can also queue\nfw_load_work.\n\nThose controls are not removed on component unbind, and device remove\nonly cancels fw_load_work through cs35l41_remove_dsp(). That helper is\nskipped when halo_initialized is false. With firmware_autostart\ndisabled, a firmware load can be requested before the DSP has been\ninitialized. If the component or device is removed before the queued\nwork runs, the worker can run after teardown and dereference driver\nstate that is no longer valid.\n\nTrack the created controls and remove them on unbind so no new control\ncallback can reach the driver data or queue more work.
