You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

This wasn't handled by the codec, instead it would set the FLL frequency to 0Hz which isn't working. Since we don't have any rate constraints just ignore this request.
