I am a Debian stable user.
My install failed and I don't know why because I am a noob.

Building module:
Cleaning build area...
make -j24 KERNELRELEASE=6.1.0-37-amd64 KVER=6.1.0-37-amd64 EXTRA_CFLAGS=''...(bad exit status: 2)
Error! Bad return status for module build on kernel: 6.1.0-37-amd64 (x86_64)
Consult /var/lib/dkms/maccel/0.5.4/build/make.log for more information.

This is the error code
