The patch
ASoC: cs4271: Increase delay time after reset
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 send followup patches addressing any
issues that are reported.
Please add any relevant lists to the CCs when replying to this mail.
Thanks,

Subject: [PATCH] ASoC: cs4271: Increase delay time after reset
The delay time after a reset in the codec probe callback was too short,
and did not work on certain hw because the codec needs more time to
power on. This increases the delay time from 1us to 1ms.
