Subject: [PATCH 3/3] udev rules: don't generate multiple vpdupdate events for
 SCSI/NVMe

lsvpd lists SCSI devices, not partitions or block devices. Currently,
addition of e.g. /dev/sda will generate events for a "scsi_device",
"scsi_disk", "bsg", and "block" device, plus events for partitions,
and every event will trigger a "touch /run/run.vpdupdate" command,
where touching the file once would be obviously sufficient. Add rules
that touch vpdupdate for SCSI hosts and devices, but not for the
additional sysfs nodes.

Similar reasoning for NVMe.
