[dm-devel] [PATCH 4/5] mpath: skip device configs without vendor/product

[Benjamin Marzinski]

Right now if multipath.conf includes a device configuration without a
vendor or product string, it will automatically be applied to all
devices, skipping all other configs entirely.  This is clearly wrong.
This patch makes sure that user added configs include vendor and
product strings
