Subject: media: vivid: add instance number to input/output names
Author: Hans Verkuil <hverkuil-ci...@xs4all.nl>
Date: Mon Jun 24 12:53:00 2024 +0300
Add the instance number before the input or output number.
So "HDMI 1" becomes "HDMI 000-1".
This is helps identifying which input or output belongs to
which vivid instance.
