We had a patch recently that was missing the inclusion of the actual patch in the SRC_URI. https://patchwork.openembedded.org/patch/156047/
Mingli, you ended up with this defect since, iirc, you sent a patch to run patchtest in a container. It seems that patchtest isn't running now so it might be that Armin just needs to get it restarted on the YP machines. Armin, do you know who manages those systems?
A change was committed and later reverted some time back to fix this: https://bugzilla.yoctoproject.org/show_bug.cgi?id=11432 I tried that change and couldn't figure out what was wrong, seemed okay to me. Perhaps that can be used as a starting point ...
Since Changqing work on patchtest and the author of the patch https://patchwork.openembedded.org/patch/156047/ also is Changqing, so forward this issue to Changqing to track.
