GPL-only symbol Error

[Sengottuvelan S]

Hi All,

Basically, I am developing a kernel module named "xyz.ko"  and my
MODULE_LICENSE is "Proprietary". I have got an error "GPL-incompatible
module xyz.ko uses GPL-only symbols".

I am having trouble identifying it. How to avoid this error in during
MODPOST?. Is there any way to avoid this error?

Can you someone throw light on this.

Regards,
S. Sengottuvelan.
