[alsa-devel] [PATCH] ASoC: sgtl5000: avoid division by zero if lo_vag is zero

From: Colin Ian King <colin.king(a)canonical.com> In the case where lo_vag <= SGTL5000_LINE_OUT_GND_BASE, lo_vag is set to zero and later vol_quot is computed by dividing by lo_vag causing a division by zero error.

[alsa-devel] Applied "ASoC: dapm: Move error handling to snd_soc_dapm_new_control_unlocked" to the asoc tree

The patch ASoC: dapm: Move error handling to snd_soc_dapm_new_control_unlocked has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 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.

[alsa-devel] Applied "ASoC: dapm: Add support for multi-CODEC CODEC to CODEC links" to the asoc tree
by Mark Brown 06 Sep '18

06 Sep '18

The patch ASoC: dapm: Add support for multi-CODEC CODEC to CODEC links has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 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 >From 4a75aae17b2a802a7267206414050408392c374c Mon Sep 17 00:00:00 2001 From: Charles Keepax <ckeepax(a)opensource.cirrus.com> Date: Wed, 5 Sep 2018 15:21:01 +0100 Subject: [PATCH] ASoC: dapm: Add support for multi-CODEC CODEC to CODEC links Currently multi-CODEC is not supported on CODEC to CODEC links. There are common applications where this would be useful, such as connecting two mono amplifiers to an audio CODEC. Adding support simply requires an update of snd_soc_dai_link_event to loop over the attached CODEC DAIs.
