I'm not requesting this out of any kernel-doc style. It's just a
personal preference and consistency in dwc3. If it's not too difficult,
please use "-". But if you must insist, future lists would need to be
consistent to this new unicode style. Then I would need to ask others to
use the new Unicode one. Typically typing * doesn't automatically
convert to • unless you edit using Word, and so I prefer something I and
others can easily find on the keyboard.

If you prefer to keep the snippet of your vendor specification intact,
we can instead document this fully in the commit message and note the
EBC feature. Remove these comments here.
