[PATCH v3 2/3] ASoC: simple-card: move hp and mic detection to soc_card probe

[Katsuhiro Suzuki]

This patch moves headphone and microphone detection to probe() of
snd_soc_card from init() of snd_soc_dai_link. This is because init()
is called (and an input device /dev/input/eventX is created too)
twice or above if simple card has two or more DAI links.

For all patches

Applied "ASoC: simple-card: move hp and mic detection to soc_card probe" to the asoc tree

[Mark Brown]

The patch

   ASoC: simple-card: move hp and mic detection to soc_card probe

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
