There was a reason for that though, the file was meant for the<br>
monochrome version of the sensor. See [1] for the full context. I'm<br>
actually aware of one user of this tuning file with a monochrome sensor,<br>
and this patch will break this use case.<br>
<br>
This brings nack the question that we decided to leave unanswered when<br>
the imx296.json file was merged: how do we deal with different modules<br>
that integrated the same camera sensor ?<br>
<br>

Our (admittedly very loose) convention is to have</div><div>the <sensor_name>.json file be the full colour variant, and any offshoot be named as</div><div><sensor_name>_<variant>.json.
