Subject: Applied "ASoC: hdmi-codec: remove multi detection support" to the asoc tree
The patch
ASoC: hdmi-codec: remove multi detection support
has been applied to the asoc tree at
git://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

Subject: [PATCH] ASoC: hdmi-codec: remove multi detection support
DesignWare HDMI driver (= dw-hdmi) is supporting HDMI sound, and its
probe function was calling sound binding function multiple times as
same HDMI device different port.
Because of this behavior, commit 9731f82d601 ("ASoC: hdmi-codec: enable
multi probe for ...") was added for multi detection case.
But, this DesignWare HDMI detection/bind code was exchanged/adjusted by
commit 69497eb9234 ("drm: bridge: dw-hdmi: Implement DRM bridge...").
Now, all DesignWare HDMI sound ports are detected as 1 bindng function.
Because of this, hdmi-codec multi detection support is no longer needed.
Thus, this patch removes
commit 9731f82d601 ("ASoC: hdmi-codec: enable multi probe for ..."),
and its related
commit 340327a62c4 ("ASoC: hdmi-codec: Fix hdmi_of_xlate_dai_name...")
commit 8480ac56795 ("ASoC: hdmi-codec: remove HDMI device unregister")
commit 0c343a35bfe ("ASoC: hdmi-codec: fix spelling mistake: ...)
