I was expecting to find some information about this new control in its DocBook documentation, but this part seems to be missing here. :) Could you please add relevant entries in Documentation/DocBook/media/v4l/controls.xml as well ? -- Regards, Sylwester -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
