Not building on SLED 15.5, the below are changes which do make it build without DRM

building WITH drm enabled fails as for other reported issues with drm/drm_irq.h #308

required to add the libkms library to avoid compile errors

zypper install libkms-devel   

modify the Makefile by commenting out

CONFIG_DRM_EVDI := m   

so it now reads

#CONFIG_DRM_EVDI := m  

• Now the module builds and install into dkms but does not install into the kernel tree with either of below warnings depending on the dkms command used (respectively build and install)
  • WARNING: Symbol version dump "Module.symvers" is missing.
