I was working on subdev internal routing between pads, and realized that there's no way to add TRY functionality for routes, which is not pad specific configuration. Adding a separate struct for try-route config wouldn't work either, as e.g. set-fmt needs to know the try-route configuration to propagate the settings. This patch adds a new struct, 'struct v4l2_subdev_config' (which at the moment only contains the v4l2_subdev_pad_config array) and the new struct is used in most of the places where v4l2_subdev_pad_config was used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config are changed to instead take v4l2_subdev_config. Two drivers are changed to work with the above changes (drivers for HW which I have) as an example. I worked on a semantic patch (included below, my first spatch...) to do this change to all drivers, but hit lots of problems with non-trivial uses of v4l2_subdev_pad_config. As it looks like substantial amount of manual work is needed, I'm posting this RFC to get an ack on the changes before continuing that work. @ v4l2_subdev_pad_ops @ identifier pad_ops; identifier func; @@ ( static const struct v4l2_subdev_pad_ops pad_ops = { ..., .enum_mbus_code = func, ..., }; | static const struct v4l2_subdev_pad_ops pad_ops = { ..., .enum_frame_size = func, ..., }; | static const struct v4l2_subdev_pad_ops pad_ops = { ..., .enum_frame_interval = func, ..., }; | static const struct v4l2_subdev_pad_ops pad_ops = { ..., .get_fmt = func, ..., }; | static const struct v4l2_subdev_pad_ops pad_ops = { ..., .set_fmt = func, ..., }; | static const struct v4l2_subdev_pad_ops pad_ops = { ..., .get_selection = func, ..., }; | static const struct v4l2_subdev_pad_ops pad_ops = { ..., .set_selection = func, ..., }; | static const struct v4l2_subdev_pad_ops pad_ops = { ..., .init_cfg = func, ..., }; ) @@ identifier v4l2_subdev_pad_ops.func; identifier sd; identifier cfg; @@ func(struct v4l2_subdev *sd, - struct v4l2_subdev_pad_config *cfg, + struct v4l2_subdev_config *cfg, ... ) { ... } @@ identifier v4l2_subdev_pad_ops.func; identifier sd; identifier cfg; @@ func(struct v4l2_subdev *sd, - struct v4l2_subdev_pad_config *cfg + struct v4l2_subdev_config *cfg ) { ... } @@ struct v4l2_subdev_fh *fh; @@ - fh->pad + &fh->cfg @@ identifier func; identifier cfg; @@ func(..., - struct v4l2_subdev_pad_config *cfg, + struct v4l2_subdev_config *cfg, ...) { ... } @@ struct v4l2_subdev_config *cfg; @@ { <...
