Hi,
My kernel version is v4.4, and I have built drivers/staging/dgnc/dgnc.ko. I change to *dir*/drivers/staging/dgnc and do like this:
sudo insmod ./dgnc.ko
Do you have the hardware that this driver controls?
sudo lsmod | grep dgnc
Does that show anything?
sudo rmmod ./dgnc sudo insmod ./dgnc.ko
After I re-insmod the dgnc module, my laptop is breakdown.
Then there's a bug to fix in the driver, it must not clean up everything properly. Based on a quick read of it, there is lots of things that need to be fixed in it, that's why it is in staging. If you are interested, I would suggest fixing this issue would be a great start. good luck! greg k-h
