Don't use __init but __devinit to define probe function. A pointer to sa11xx_uda1341_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_SA11XX_UDA1341=m the following probably oopses:

echo -n sa11xx_uda1341.1 > /sys/bus/platform/driver/sa11xx_uda1341/unbind echo -n sa11xx_uda1341.1 > /sys/bus/platform/driver/sa11xx_uda1341/bind

--- Hello,

uups, I forgot to add the right cc:. Sorry.

@Andrew, I have a few more patches of this type pending. Is it OK for you if they go via you? This would ease the process a bit for me.
