Subject: Re: [PATCH v2 1/4] usb: typec: ucsi: Fix null deref in trace

It looks like in v3 you changed this to:

-       return NULL;
+       return typec_port_register_altmode(con->port, desc);

Which is fine.  Returning a special error pointer which means success is
the part that I objected to.

regards,
