[1/2] ASoC: cs42l43: Don't enable bias sense during type detect commit: dc96528b176fa6e55a3dc01060fe9d97be450ce9 [2/2] ASoC: cs42l43: Allow HP amp to cool off after current limit commit: bbbc18d8c27cc9d40cc9a3b03b61e4df85311146 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

Alas on some headsets the bias sense can cause problems with the type detection. It can occasionally be falsely triggered by the type detect itself and as the clamp is applied when this happens, it will cause a headset to be incorrectly identified as headphones. As such it should be disabled whilst running type detect. This does mean a jack removal during type detect will cause a larger click but that is unfortunately unavoidable.
