The same warnings are also being reported when I compile my external

Is there any suggestions on how to solve this problem...?

thanks in advance..

Yes. Don't call functions marked with __init or __devinit from inside
functions not marked with these special keywords.

Thanks for helping .Anyway to remove this warning at all either while
compiling the kernel or compiling the external module.
