What tree is this? Sorry for this false alarm. The test was run on a separate tree created by the robot for testing the patch. > Why does it contain: > > backlight: ktz8866: Add support for Kinetic KTZ8866 backlight > > But not: > > dt-bindings: leds: backlight: Add Kinetic KTZ8866 backlight Refer to the patch link: https://lore.kernel.org/all/20230127152639.1347229-1-u.kleine-koenig@xxxxxxxxxxxxxx/ 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 -- Best Regards, Yujie
