[PATCH 4.20 063/352] media: vivid: fill in media_device bus_info

[Greg Kroah-Hartman]

4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit e10b40f3304360d3a2d07d690ff12197f828f2c8 ]

If you create multiple vivid instances, each with their own media
device, then there was no way to tell them apart.

Fill in the bus_info so each instance has a unique bus_info string.
