Formatting done via: git ls-files | grep -E '.*\.m$' | xargs clang-format -i After applying the command, I manually excluded Matlab .m files that I will handle separately. No-Iwyu: Includes didn't change and it isn't related to formatting Bug: webrtc:42225392 Change-Id: I40d11fd6b650ee0d90d92cbd6fc6aa6c78e1fea3 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/373887 Commit-Queue: Harald Alvestrand <hta@webrtc.org> Reviewed-by: Danil Chapovalov <danilchap@webrtc.org> Reviewed-by: Harald Alvestrand <hta@webrtc.org> Cr-Commit-Position: refs/heads/main@{#43706}
