Hello,
There is option in menu->"Device Drivers"->"Generic Driver
Options"->"External firmware blobs to build into the kernel binary".
I have used this many times instead of /lib/firmware mechanism. If
someone chooses to add firmware in that way, and gives different name,
then this code too can break. So I have proposed another way to solve
that. Have a look into this.
Regards,
Subash

Hi Sachin,
Thanks for the patch. I agree with you - MFC module could be used in other
SoCs as well.

This patches renames the MFC firmware binary to avoid SoC name in it.
