[Bug 378989] [NEW] scsi controller aic7xxx should set name scanner and permissions automaticly

[HAMcZlaw]

Public bug reported:

My scanner HP ScanJet 4c  use scsi controller aic7xxx. This controller
know to be scanner controller only. At the momment this controller have
permissions to root only. I think it will be nice to have this
controller configured with udev by default to /dev/scanner with saned
group or some thing like this.

udevadm info -a -p /sys/class/scsi_generic/sg3

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
