I guess there is no use in always returning 0, simply not returning anything and
putting a void type might be cleaner, especially as this function
seems to never
return.

Hum perhaps it does not like the comparision of a __u16 and an unsigned int ?

I enclose some dummy patch that should perhaps solve these issues,
could not test it as i don't have the hardware... just my 2 cents.
Don't know if casting is an
acceptable workaround though.
