| Subject: media: imx: set a media_device bus_info string |
| |
| From: Martin Kepplinger <martin.kepplinger@puri.sm> |
| |
| [ Upstream commit 6d0d779b212c27293d9ccb4da092ff0ccb6efa39 ] |
| |
| Some tools like v4l2-compliance let users select a media device based |
| on the bus_info string which can be quite convenient. Use a unique |
| string for that. |
| |
| This also fixes the following v4l2-compliance warning: |
| warn: v4l2-test-media.cpp(52): empty bus_info |
