build error on debian

[treaki]

i followed your guide on debian testing, but:

$ sudo dkms build -m ${DRV_NAME} -v ${DRV_VERSION}

Kernel preparation unnecessary for this kernel.  Skipping...

add this to include/osdep_service.h

#include <linux/version.h> #if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 11, 0) #include <linux/sched/signal.h> #endif
