The patch
ASoC: Intel: Skylake: Use the sig_bits to define dai bps capability
has been applied to the asoc tree at
git://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

Subject: [PATCH] ASoC: Intel: Skylake: Use the sig_bits to define dai bps
capability
For calculating the HDA DMA format, use the max_bps supported by the
DAI caps instead of fixing it to 32/24. For host DMA the Max bps support
is 32, but in case of link DMA, this depends on the codec capability.
So use the sig_bits to define the bps supported by dai.
