Buildroot is a tool that build various software packages. The patches being removed are usually for packages that Buildroot patches to fix the build. These patches are often pulled from upstream git repo of respective package. When the package version updates, the patch is dropped.
We don't cc patch authors when we add the patch in the first place, because the regexp does not match '+Signed-off-by'. I see not reason to cc them when we remove the patch.
