Commit 93d3672 breaks the camera on Lenovo ThinkPad X1 carbon gen 12 models.

These laptops have a 'CJFME55' sensor module id, so I think this may be related to this part of the change:

-        <supportedTuningConfig value="NORMAL,VIDEO,OV08X40_CJFME55_MTL,
-                                      STILL_CAPTURE,VIDEO,OV08X40_CJFME55_MTL"/>
+        <supportedTuningConfig value="NORMAL,VIDEO,OV08X40_BBG802N3_RG_MTL,
+                                     STILL_CAPTURE,VIDEO,OV08X40_BBG802N3_RG_MTL"/>

After this change I get the following output launching a gst pipeline with icamerasrc:

Cc @drhooray this breakage is caused by a recent change from you, can you take a look please?

[drhooray]

Thanks for the heads up, Hans.

Because the patch also requires driver patches.
The driver patches are currently under internal review. Once they are approved to upstream. I will update the status.

You can assign the issue to me for tracking.
