While I don't fancy this way of structuring device drivers in Linux, I think it's reasonable to retain that design for now, and perform the parsing and power initialization in dp_display_probe(). > + if (rc) { > + DRM_ERROR("device tree parsing failed\n"); > + goto error; > + } > + > dp->catalog = dp_catalog_get(dev, &dp->parser->io); > if (IS_ERR(dp->catalog)) { > rc = PTR_ERR(dp->catalog); > @@ -768,6 +768,12 @@ static int dp_init_sub_modules(struct dp_display_private *dp) > goto error; > } > > + rc = dp_power_client_init(dp->power); > + if (rc) { > + DRM_ERROR("Power client create failed\n"); > + goto error; > + } > + > dp->aux = dp_aux_get(dev, dp->catalog, dp->dp_display.is_edp); > if (IS_ERR(dp->aux)) { > rc = PTR_ERR(dp->aux); > @@ -1196,26 +1202,20 @@ static irqreturn_t dp_display_irq_handler(int irq, void *dev_id) > return ret; > } > > -int dp_display_request_irq(struct msm_dp *dp_display) > +static int dp_display_request_irq(struct dp_display_private *dp) > { > int rc = 0; > - struct dp_display_private *dp; > - > - if (!dp_display) { > - DRM_ERROR("invalid input\n"); > - return -EINVAL; > - } Love this, but it's unrelated to the rest of the patch. > - > - dp = container_of(dp_display, struct dp_display_private, dp_display); > + struct device *dev = &dp->pdev->dev; > > - dp->irq = irq_of_parse_and_map(dp->pdev->dev.of_node, 0); > if (!dp->irq) { > - DRM_ERROR("failed to get irq\n"); > - return -EINVAL; > + dp->irq = irq_of_parse_and_map(dp->pdev->dev.of_node, 0); > + if (!dp->irq) { > + DRM_ERROR("failed to get irq\n"); > + return -EINVAL; > + } > } > > - rc = devm_request_irq(dp_display->drm_dev->dev, dp->irq, > - dp_display_irq_handler, > + rc = devm_request_irq(dev, dp->irq, dp_display_irq_handler, This is fixing a bug where currently the dp_display_irq_handler() registration is tied to the DPU device's life cycle, while depending on resources that are released as the DP device is torn down. It would be nice if this was not hidden in a patch that claims to just move calls around.
