DKMS build errors with kernel 6.8.0-52-generic

[hernanmd]

BTW this is kind of a "default" or "standard" Ubuntu installation:

Distributor ID:	Ubuntu
Description:	Ubuntu 22.04.5 LTS
Release:	22.04
Codename:	jammy

Using the code in this repository (which supposedly has a patch to make it work in "newer" kernels like 6.8...) I've successfully built and installed the package using dpkg -i gasket-dkms_1.0-18_all.deb in Ubuntu 22 for the kernel 6.8.0-52-generic.

But when I try to build the module:

sudo dkms build -m gasket-dkms -v 1.0-18
sudo dkms install -m gasket-dkms -v 1.0-18

I get these errors:

Kernel preparation unnecessary for this kernel. Skipping...

Make sure the name of the generated module is correct and at the root of the

/var/lib/dkms/gasket-dkms/1.0-18/build/ for more information.

This is my /usr/src/gasket-dkms-1.0-18/dkms.conf

The make.log does not seem to contain too much information
