Subject: [PATCH 0/3] coresight: Alloc trace ID after building the path

Proof of concept to support CTCU device. Applies to Jie's patchset in
the parent email. I think this would be a good simplification, it
removes some code and makes things a bit clearer, and works for both the
old and new CTCU requirements. It will require merging into the parent
patchset somehow as it undoes some of those changes.

James Clark (3):
  coresight: Don't save handle in path
  coresight: Export coresight_get_sink()
  coresight: Alloc trace ID after building the path
