Vendor field with USB, [SP]ATA etc-attached disks

[Michael Tokarev]

With current SATA, PATA and at least some USB disks,
Linux reports Vendor: $subsystem, instead of the actual
vendor of the drive, like this:

scsi1 : ata_piix
  Vendor: ATA       Model: ST3808110AS       Rev: n/a
  Type:   Direct-Access                      ANSI SCSI revision: 05

This should be Vendor: Seagate, not ATA (Note also the lack
of "Revision" field).  The same for PATA disk:

scsi0 : pata_via
  Vendor: ATA       Model: ST3120026A        Rev: 3.76
  Type:   Direct-Access                      ANSI SCSI revision: 05

The same is shown in /sys/block/$DEV/device/vendor.

Can it be changed to show real vendor, instead of the subsystem name?

Thanks.
