Hi Joe,

Sorry, i am not sure how KBUILD_MODNAME is compiled by kernel.

If i am not wrong KBUILD_MODNAME would work only for drivers that can
be added as module? If so, then it may not apply here, as most of the stuff
i have updated doesn't call module_init().

So, if i try KBUILD_MODNAME with my patch i get prints as:

KBUILD_MODNAME: <print - text>
