Applied to kbuild/linux.git (kbuild-next-unstable), thanks!

[1/2] scripts/config: Use POSIX standard ERE (-E) in sed
      https://git.kernel.org/kbuild/c/1d553517
[2/2] scripts/config: Use in-place editing (-i) in sed portably
      https://git.kernel.org/kbuild/c/005d6382

Please look out for regression or issue reports or other follow up
comments, as they may result in the patch/series getting dropped,
reverted or modified (e.g. trailers).

Patches applied to the kbuild-next-unstable branch are accepted pending
wider testing in linux-next and any post-commit review; they will
generally be moved to the kbuild-next branch in about a week if no
issues are found.

Best regards,
