ALSA: Fix section for snd-aica platform 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.
