What I have in the tree, is what I have merged. If you have
dependencies that aren't in my tree, send them as part of a

The copy of the patch that failed is found in:
/home/bruce/poky-kernel/linux-yocto-4.12.git/.git/rebase-apply/patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".

Can you double check that the 4.12 you used to generate this series
matches what I have staged on git.yoctoproject.org.
