[PATCH] ASoC: tlv320adc3xxx: Fix buggy return value
snd_soc_component_update_bits returns 1 if the operation was successful and some bits were changed, so we cannot return this value directly as it can be interpreted as an error. Instead, do some minor mangling to avoid inadvertently returning an error.

Thanks!
[1/1] ASoC: tlv320adc3xxx: Fix buggy return value commit: eb8b5af702ca0b9adbccec1ddd944a282c57aa66
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
