Root cause for the mmc complain is that there is no handler for function 
2 interrupt. 4329 generate a SDIO interrupt when there are something 
available for the driver to retrieve from the dongle. It will flag both 
function 1 and function 2 at the same time. They are identical. A empty 
dummy irq handler register to function 2 irq will make the warning go 
away. FWIW, it doesn't affect anything here since they have been taken 
care in function 1 irq handler. I will submit a patch too add the dummy 
handler.

Thanks,
Franky
