Sorry for my late reply.

Yes, if you want, I will give it a try.

Andrew picked up my patch already as its been sitting in limbo without
any feedback for a long time --- so you can work off of what is on
linux-next or we can request Andrew to drop this patch once and if you
get a replacement as its not yet on Linus' tree.

It is not a good idea to make your work stuck even longer.

Please go ahead with your patch.


When I find time to take a close look,
I may come back to firmware/Makefile.
But, I guess it will not happen soon.
