[PATCH 0/3] ASoC: rt5682: fix Kconfig/compilation issues when I2C is not selected

[Pierre-Louis Bossart]

RT5682 can work in I2C or SoundWire mode, but the code will not
compile if I2C is not selected.

[PATCH 1/3] ASoC: rt5682: fix unmet dependencies

[Pierre-Louis Bossart]

The rt5682 code can be used in I2C or SoundWire mode. When I2C is not
selected, we have the following issue:

WARNING: unmet direct dependencies detected for SND_SOC_RT5682
  Depends on [n]: SOUND [=m] && !UML && SND [=m] && SND_SOC [=m] &&
  I2C [=n]
  Selected by [m]:
  - SND_SOC_RT5682_SDW [=m] && SOUND [=m] && !UML && SND [=m] &&
    SND_SOC [=m] && SOUNDWIRE [=m]

Fix by adding SOUNDWIRE as a dependency.

I think it would be better to do this by factoring the bus code out into
a separate file like we've done with I2C and SPI, it's neater than
ifdefs and easier to get right going forwards.

[Mark Brown]

The patch

   ASoC: rt5682-sdw: fix 'defined but not used' pm functions

has been applied to the asoc tree at

   https://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

The rt5682 code can be used in I2C or SoundWire mode. When I2C is not
selected, we have the following issue:

WARNING: unmet direct dependencies detected for SND_SOC_RT5682

Fix by adding SOUNDWIRE as a dependency.

Agree, this was just a quick fix to solve compilation issues.
