You should use v4l2_subdev_call() instead. This will obviously not be enough if we have more than one subdev in the pipeline, but the code is broken in that case anyway. > if (ret < 0) > - return ret; > + goto cleanup; > > v4l2_fill_pix_format(pix, &format.format); > > @@ -121,6 +127,8 @@ static int __rvin_try_format_source(struct rvin_dev > *vin, vin_dbg(vin, "Source resolution: %ux%u\n", source->width, > source->height); > > +cleanup: Nitpicking, I'd name the label "done". > + v4l2_subdev_free_pad_config(pad_cfg); > return 0; > } -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
