Do you think this is a better approach? This will save work if other drivers want to cache devargs list for device hot plug events.

Agree, that having devargs be smart enough to maintain the list for future hotplug is sensible.
Do other drivers that support hotplug have the same issue, or does no one ever use devargs with things like failsafe.
