I'm now going to format all C files as well. Formatting done via: git ls-files | grep -E '^common_audio/signal_processing.*\.c$' | xargs clang-format -i I split it because there are many formatting changes, so its easier to review. No-Iwyu: Includes didn't change and it isn't related to formatting Bug: webrtc:42225392 Change-Id: Ic0f1752aa670984f8cda665dc2ef03ad32581797 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/373886 Reviewed-by: Harald Alvestrand <hta@webrtc.org> Commit-Queue: Harald Alvestrand <hta@webrtc.org> Reviewed-by: Danil Chapovalov <danilchap@webrtc.org> Cr-Commit-Position: refs/heads/main@{#43697}
