[PATCH] ASoC: hdmi-codec: fix missing report for jack initial status
This fixes a problem introduced while fixing ELD reporting with no jack set.
Most driver using the hdmi-codec will call the 'plugged_cb' callback directly when registered to report the initial state of the HDMI connector.
With the commit mentionned, this occurs before jack is ready and the initial report is lost for platforms actually providing a jack for HDMI.
Fix this by storing the hdmi connector status regardless of jack being set or not and report the last status when jack gets set.
With this, the initial state is reported correctly even if it is disconnected. This was not done initially and is also a fix.

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
