What's going on here?  What tree is this?

Why does it contain:

  backlight: ktz8866: Add support for Kinetic KTZ8866 backlight

But not:

  dt-bindings: leds: backlight: Add Kinetic KTZ8866 backlight

Sorry for this false alarm.

The test was run on a separate tree created by the robot for testing
the patch.

Refer to the patch link:
https://lore.kernel.org/all/20230127152639.1347229-1-u.kleine-koenig@pengutronix.de/

It has the following base tree info:

base-commit: 2241ab53cbb5cdb08a6b2d4688feb13971058f65  <-- this is v6.2-rc5
prerequisite-patch-id: 2e7d7db8c0a90b8cd1deb6bbc51ead4c89c89b62  <-- this is "backlight: ktz8866: Add support for Kinetic KTZ8866 backlight"

So the story is:
* the robot checkout to v6.2-rc5, and create a new branch for testing above patch
* apply prerequisite patch "backlight: ktz8866: Add support for Kinetic KTZ8866 backlight"
* apply patch "backlight: ktz8866: Convert to i2c's .probe_new()"
* run tests, then this false report was generated

But actually it also needs "dt-bindings: leds: backlight: Add Kinetic
KTZ8866 backlight" as prerequisite.

There will be no problem if the patch has a complete base tree info
like:

base-commit: 2241ab53cbb5cdb08a6b2d4688feb13971058f65
prerequisite-patch-id: 612774e516227f109175b3f3faeff937104e9cad
prerequisite-patch-id: 2e7d7db8c0a90b8cd1deb6bbc51ead4c89c89b62
