* Description: Implementation of a driver that fakes driver version. It
* is used for checking that version mismatches are handled
* correct by the emulator. The following makros have to be
* defined before it can be used:
* * VSN_MISMATCH_DRV_NAME_STR
* * VSN_MISMATCH_DRV_NAME
* * VSN_MISMATCH_DRV_MAJOR_VSN_DIFF
* * VSN_MISMATCH_DRV_MINOR_VSN_DIFF
