[alsa-devel] [PATCH] ASoC: Intel: Skylake: Fix to turn off hdmi power on probe failure
From: "Sodhi, VunnyX" vunnyx.sodhi@intel.com
HDMI codec is required to be powered up before controller initialization for successful enumeration of codec. If the probe fails it needs to be powered off to balance the power state of HDMI codec.
This fix balances the reference count in the error path before turning off the codec.

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.
