The patch
ASoC: cs4349: Fix suspend/resume
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

dev_get_drvdata() will not return the snd_soc_runtime to which this CODEC is attached, so the current code will result in undefined behavior. To fix this just use regmap_update_bits(cs4349->regmap, ...) directly instead of snd_soc_update_bits(rtd->codec, ...).
