Hello Hannes,

So for some entries in the table a prefix match should be performed (e.g. the
model string for the Hitachi entry) but for other entries (e.g. the scanner
entry) an exact match should be performed on the vendor name? If so, how about
one of the following two approaches:
* Adding ".*" at the end of the entries in the table for which a prefix match
  is sufficient and to change scsi_dev_info_list_find() such that it performs
  a regex match instead of an exact match or a prefix match.
* Performing an exact match on the vendor name and a prefix match on the model
  name.

Thanks,

Bart.
