[1/2] ASoC: ops: add correct range check for limiting volume commit: fb9ad24485087e0f00d84bee7a5914640b2b9024 [2/2] ASoC: qcom: sc8280xp: Limit speaker digital volumes commit: 716d4e5373e9d1ae993485ab2e3b893bf7104fb1 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. 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. Thanks, Mark

Oops, no, this breaks the build on 6.6.y, can you send a series that is at least built for this series successfully? :) thanks, greg k-h
From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Limit the speaker digital gains to 0dB so that the users will not damage them. Currently there is a limit in UCM, but this does not stop the user form changing the digital gains from command line. So limit this in driver which makes the speakers more safer without active speaker protection in place. Apart from this there is also a range check fix in snd_soc_limit_volume to allow setting this limit correctly. Tested on Lenovo X13s.
