Subject: Applied "ASoC: samsung: i2s: Fix DAPM routes for capture stream" to the asoc tree

The patch

   ASoC: samsung: i2s: Fix DAPM routes for capture stream

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

Subject: [PATCH] ASoC: samsung: i2s: Fix DAPM routes for capture stream

This patch sets missing stream_name of capture part of the DAI driver
so we can define DAPM routing properly also for the capture stream.

While at it "Playback" suffix is added to the playback stream names
to clearly identify playback/capture.

Together with related dts patch this fixes NULL pointer dereference
when opening ALSA device for recording on Odroid XU3.
