[sane-devel] [patch] fix SCSI device matching

[Tim Waugh]

When a SCSI device returns a blank string field (such as the vendor
field), sanei_scsi_find_devices gets confused.

See <https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=55092>.

I append a patch that I think will fix it.  What do you think?

Tim.
