Hello Cate,
You can remove a driver by unlinking the device node and closing all
open references to the driver (provided that the driver properly
implements the unlink method.)
nsh> rm /dev/node is one way.
Calling unlink() is another.
What exactly are you willing to do? Could you please describe your use case?
BR,
Alan
