Hi Jiri

You can see in the third version the core code accept a free form
name. The driver builds a name using the driver name and the adaptor

What i think would be good is to try to have one API to the driver
that can be used for both crash dumps and devlink snapshots. These are
used at different times, but have basically the same purpose, get
state from the device.
