Subject: [PATCH] media: imx: set a media_device bus_info string
Date: Wed,  8 Sep 2021 10:47:46 +0200	[thread overview]
Message-ID: <20210908084746.243359-1-martin.kepplinger@puri.sm> (raw)

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
