[PATCH v5 1/2] ASoC: rt5575: Add the codec driver for the ALC5575
This codec driver is for the ALC5575 that has a built-in audio DSP. The firmware can be loaded by the SPI from the SOC or the external flash.

Missing changelog.
<form letter> Please use scripts/get_maintainers.pl to get a list of necessary people and lists to CC. It might happen, that command when run on an older kernel, gives you outdated entries. Therefore please be sure you base your patches on recent Linux kernel.
Tools like b4 or scripts/get_maintainer.pl provide you proper list of people, so fix your workflow. Tools might also fail if you work on some ancient tree (don't, instead use mainline) or work on fork of kernel (don't, instead use mainline). Just use b4 and everything should be fine, although remember about `b4 prep --auto-to-cc` if you added new patches to the patchset.
You missed at least devicetree list (maybe more), so this won't be tested by automated tooling. Performing review on untested code might be a waste of time.
Please kindly resend and include all necessary To/Cc entries. </form letter>
Best regards, Krzysztof
Hi Oder,

Thanks!
[1/2] ASoC: rt5575: Add the codec driver for the ALC5575 commit: c7ac7499ac5bb50ab3e00add121822c5c904bc91 [2/2] ASoC: dt-bindings: realtek,rt5575: add bindings for ALC5575 (no commit info)
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
