hw-mgmt: scripts: Fix hotplug events for dpu
Browse files Browse the repository at this point in the history 
DPU power/health events were not updated in the
/var/run/hw-management/dpu*/events folder. It was due to
the fact that attributes did not have the dpu slot number
in the attribute name. This patch introduces a new tag
'hotplug-dpu-event' and an action function to find out
the dpu slot number, which is used to derive the event
attribute path.
