* About THIS_MODULE

Hi all,
I have a query which I hope someone can advise on.
I am adding a library API which requires a driver to pass the driver
module pointer to the API.
So we use THIS_MODULE for that purpose.
However, adding a sanity check in the library to ensure that pointer is
set is a challenge. Normally we would check that the module pointer is
non-NULL. However, for a built-in driver module, THIS_MODULE is NULL, so
rely on the non-NULL check.
Any idea how to deal with this?
Cheers
