IIUC, MODULE_FIRMWARE is only necessary for devices that need firmware
to operate.  vxge hardware has an image in flash on the nic, and the
modified code is used to update the firmware image on the adapter.
So, this change isn't doing what you want it to do.

Also, wasn't this already discussed (https://lkml.org/lkml/2012/4/12/401)?

Thanks,
Jon

Hmm, I'd forgotten about that discussion, but its no more correct now 
then it was then. MODULE_FIRMWARE is purely informational and has _no_ 
runtime impact. It is merely an indicator that a firmware file _might_ 
be used by the kernel and should therefore be left in the external 
firmware package. MODULE_FIRMWARE() uses the same base MODULE_INFO macro 
as MODULE_VERSION, MODULE_AUTHOR, MODULE_LICENSE, etc.
