The chance of collision is slim, but still not impossible.

When you mean collision, do you mean node id collision due to bridged nodes?
Because, even if the directly connected QAIC devices use 32bit node ids, the
collision won't affect the functionality.

As in ep_nid of one device matching the nid of another device. In MHI,
that shouldn't
really matter since this patch moves away from using QRTR_EP_NID_AUTO in node
assignment, but as you mentioned below, it could clash with TUN and SMD EPs that
are already registered with their ep_nid.

Also, there is a collision with SMD and TUN endpoints, but that's out of scope
for this series.

I have not worked on a system that simultaneously uses different types of EPs;
only MHI EPs. But if there is a real case of that, we can move to
global ID assignment
that includes SMD and TUN.
