The patch
ASoC: tegra: Revert 24 and 32 bit support
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: Jon Hunter jonathanh@nvidia.com Date: Fri, 31 Jan 2020 09:19:01 +0000 Subject: [PATCH] ASoC: tegra: Revert 24 and 32 bit support
Commit f3ee99087c8ca0ecfdd549ef5a94f557c42d5428 ("ASoC: tegra: Allow 24bit and 32bit samples") added 24-bit and 32-bit support for to the Tegra30 I2S driver. However, there are two additional commits that are also needed to get 24-bit and 32-bit support to work correctly. These commits are not yet applied because there are still some review comments that need to be addressed. With only this change applied, 24-bit and 32-bit support is advertised by the I2S driver, but it does not work and the audio is distorted. Therefore, revert this patch for now until the other changes are also ready.
Furthermore, a clock issue with 24-bit support has been identified with this change and so if we revert this now, we can also fix that in the updated version.
