*
* 2-July-2001 Matt Domsch <Matt_Domsch@dell.com>
* Additional structures displayed per SMBIOS 2.3.1 spec
*
* 8/3/02 Enhanced and incorporated in lm_sensors 2.6.5
* 13-December-2001 Arjan van de Ven <arjanv@redhat.com>
* Fix memory bank type (DMI case 6)
*
* 3-August-2002 Mark D. Studebaker <mds@paradyne.com>
* Better indent in dump_raw_data
* Fix return value in dmi_bus_name
* Additional sensor fields decoded
* Fix compilation warnings
*
* 6-August-2002 Jean Delvare <khali@linux-fr.org>
* Reposition file pointer after DMI table display
* Disable first RSD PTR checksum (was not correct anyway)
* Show actual DMI struct count and occupied size
* Check for NULL after malloc
* Use SEEK_* constants instead of numeric values
* Code optimization (and warning fix) in DMI cases 10 and 14
* Add else's to avoid unneeded cascaded if's in main loop
* Code optimization in DMI information display
* Fix all compilation warnings
*
* 9-August-2002 Jean Delvare <khali@linux-fr.org>
* Better DMI struct count/size error display
* More careful memory access in dmi_table
* DMI case 13 (Language) decoded
* C++ style comments removed
* Commented out code removed
* DMI 0.0 case handled
* Fix return value in dmi_port_type and dmi_port_connector_type
