[Prunus]

Hello,
I have a problem when I run make all

# make all
make -C /lib/modules/5.15.0-2-amd64/build M=/home/prunus/git/hid-tminit modules
make[1] : on entre dans le répertoire « /usr/src/linux-headers-5.15.0-2-amd64 »

Can you help me ?

I have vmlinux here :

/boot/vmlinux.xz
/usr/src/linux-headers-5.14.0-2-common/arch/arm/include/asm/vmlinux.lds.h
/usr/src/linux-headers-5.14.0-2-common/arch/s390/include/asm/vmlinux.lds.h
