It doesn't need to allocate fbmode. > + > + ret = of_get_fb_videomode(dev->of_node, fbmode, -1); What is -1? use OF_USE_NATIVE_MODE instead including "of_display_timing.h" and just change the above code like below, fbmode = &pdata->panel.timing; ret = of_get_fb_videomode(dev->of_node, fbmode, OF_USE_NATIVE_MODE); > + if (ret) { > + DRM_ERROR("failed: of_get_fb_videomode()\n" > + "with return value: %d\n", ret); > + return ret; > + } > + pdata->panel.timing = (struct fb_videomode) *fbmode; remove the above line. > + > + pctrl = devm_pinctrl_get_select_default(dev); > + if (IS_ERR_OR_NULL(pctrl)) { > + DRM_ERROR("failed: > devm_pinctrl_get_select_default()\n" > + "with return value: %d\n", PTR_RET(pctrl)); > + return PTR_RET(pctrl); > + } > + > + } else { > + pdata = pdev->dev.platform_data; > + if (!pdata) { > + DRM_ERROR("no platform data specified\n"); > + return -EINVAL; > + } > } > > panel = &pdata->panel; > -- > 1.7.9.5 > > _______________________________________________ > dri-devel mailing list > dri-devel@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/dri-devel _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/dri-devel
