The patch
ASoC: hdmi-codec: avoid limiting params->msbits in hw_params()
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

Limiting the value of the passed in params->msbits in the hw_params() callback is redundant on three counts:
1. We already specify in the DAI driver that we can only handle up to 24 bits. This means msbits will be limited to 24 via the ALSA constraints imposed by the ASoC core, unless we have multiple codecs that can handle more bits.
2. Nothing in our hw_params() implementation uses this value.
3. The copy of the params that we are passed by the ASoC core never reads back the msbits value.
Consequently, this code is unnecessary and does nothing useful. Remove it.
