From f0e10d0a971c43fb2035fccc06de8bdd22674ec9 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Sun, 19 Feb 2023 13:09:00 +0100 Subject: media: v4l: async: Make V4L2 async match information a struct MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Make V4L2 async match information a struct, making it easier to use it elsewhere outside the scope of struct v4l2_async_subdev. Also remove an obsolete comment --- none of these fields are supposed to be touched by drivers.
