Displaylink Driver not installing

[Igor Lopez]

Same issue here, Ubuntu 20.04
My two DisplayPorts worked as expected until an update went thru.

Found several erros in the make.log file:

/var/lib/dkms/evdi/1.7.0/build/evdi_drv.c:92:3: error: ‘struct drm_driver’ has no member named ‘gem_free_object’; did you mean ‘gem_open_object’?

Where do we report this?
