ncr_tekram_eeprom

[Arkady Kuleshov <arkadio_(_at_)_gmx_(_dot_)_net>]

Although the ncr driver is marked "old"
it works for me with my Tekram DC-390U and IBM DNES UltraSCSI drive.

However if option READ_TEKRAM_EEPROM is enabled, the current
sources miss prototypes for 1 function.

#ifdef NCR_TEKRAM_EEPROM
struct            tekram_eeprom;
static int        read_tekram_eeprom(ncb_p np, struct tekram_eeprom *buffer);
#endif
