 * 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
