Subject: [PATCH 6/9] accel/habanalabs: use parent device for trace events
From: Tomer Tayar <ttayar@...ana.ai>
Trace events might still be recorded after the accel device is released,
while the device name is no longer available.
Modify the trace functions to use the parent device instead, which is
available at that point and still informative as the device name.
