From: Ricardo Ribalda <ribalda@chromium.org>

[ Upstream commit ea2b9a33711604e91f8c826f4dcb3c12baa1990a ]

bus_info field had a different value for the media entity and the video
device.

Fixes v4l2-compliance:

v4l2-compliance.cpp(637): media bus_info 'PCI:0000:00:05.0' differs from
V4L2 bus_info 'PCI:viewfinder'
