The patch

ASoC: hdac_hdmi: Fix possible memory leak in hw_params

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.

It's possible for hw_params to be called two times. So add NULL check to prevent memory leak.

In dai startup, driver was checking for ELD and would fail if no monitor is connected. This causes userland like PA, CRAS to be unhappy as they scan the device list at bootup.

So move the ELD check to hw_params and fail if valid ELD is not found.

The SKL also supports HDMI output so in probe we need to enable the HDMI using common i915 APIs to ensure it gets probed on the bus

After S3 during the controller resequencing the codec domain need to be kept ON for successful reconfiguration of Codec. Once configured it will be turned OFF in codec driver.
