Please submit patches using subject lines reflecting the style for the subsystem, this makes it easier for people to identify relevant patches. Look at what existing commits in the area you're changing are doing and make sure your subject lines visually resemble what they're doing. There's no need to resubmit to fix this alone.

What would be the appropriate subject line for Documentation/devicetree/bindings/sound Oops, I have missed the dt- prefix for the bindings for sure. - Péter Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.

I prefer ASoC: but yeah, you missed dt-.

On boards where the RST line is not pulled up, but it is connected to a GPIO line this property must present in order to be able to enable the codec.
