This is what pr_fmt is for, please just set that properly and all will
be fine.

But really, just delete this line, drivers, if all is going well, should
not emit any noise to the kernel log.  Especially for something like
doing a 'modprobe', which is really what is happening here.  Just drop
the noisy messages please.

Also, GASKET_FRAMEWORK_VERSION means nothing now, it needs to be dropped :)

thanks,
