error while installing staging kernel GKH

Hi,

I was following the tutorial on how to build your first patch and came across this error when running
sudo make modules_install install

this is the staging tree GKH.

cat /var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/make.log

returns the following message:

the question is should I report a bug on a staging driver? and how this could be fixed? did the alloc_netdev function changed? this kernel was compiled with make allyesconfig
Thanks,
PD: I am a Kernel newbie trying to commit my first patch... Sorry if this is not the right mailing list
