In particular, it will return error 48 (ENOTSUP) if the disk has an EFI label. VTOC disk labels are already handled by directly reading the disk in block/partitions/sun.c (enabled by CONFIG_SUN_PARTITION which defaults to y on SPARC). Since port->label is unused in the driver, remove the call and the field. Signed-off-by: Dwight Engen Signed-off-by: David S.
