grep backport_dependency_symbol /lib/modules/$(uname -r)/modules.symbols
alias symbol:backport_dependency_symbol mlx_compat

# strings /lib/modules/4.9.0-7-amd64/updates/dkms/mlx_compat.ko

shows 'backport_dependency_symbol' to be present, but it is currently
beyond me to find out what for :(

Other random bits and pieces:
