Newer kernels break `dpkg-buildpackage`

[groundsada]

If you are running a newer kernel than the one you are trying to patch, you will get:

dpkg-buildpackage: error: debian/rules build subprocess returned exit status 2

Please use make oldconfig

This fixed it:

# Navigate to the linux source directory (mine is at the root dir)
cd /linux

# start the editable menuconfig UI
make menuconfig

# Navigate to: 
# Cryptographic API
#    > Certificates for signature checking
#       > X.509 certificates to be preloaded into the system blacklist keyring
# Change the 'debian/certs/debian-uefi-certs.pem' string to ''

# Save your .config and exit the menuconfig UI

I used make oldconfig to replace the ones in sh，and Change the 'debian/certs/debian-uefi-certs.pem' string to '' ，but still reporting an error

If you'd like, I forked the repo, applied a fix and built the kernels: https://github.com/groundsada/linux-acs-override
