SubjectApplied "ASoC: rt5677: fall back to DT prop names on error" to the asoc tree
Date
The patch

ASoC: rt5677: fall back to DT prop names on error

has been applied to the asoc tree at

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.3

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: rt5677: fall back to DT prop names on error

The rt5677 driver uses ACPI-style property names to read from the
device API. However, these do not match the property names in _DSD
used on the Chromebook Pixel 2015, which are closer to the Device Tree
style. Unify the two functions for reading from the device API so that
they try ACPI-style names first and fall back to the DT names on error.

With this patch, plugging and unplugging the headphone jack switches
between headphones and speakers automatically.
