driver Don't use __init but __devinit to define probe function. A pointer to snd_aica_probe is passed to the core via platform_driver_register and so the function must not disappear after the module is loaded. Using __init and having HOTPLUG=y and SND_AICA=m the following probably oopses: echo -n AICA > /sys/bus/platform/driver/AICA/unbind echo -n AICA > /sys/bus/platform/driver/AICA/bind Strange enough add_aicamixer_controls which is only called by snd_aica_probe was already using __devinit. While at it move the remove function to .devexit.text section.
