Message-ID: <20141216115128.GA9761@mwanda> (raw)
Hello Mark Yao,
The patch 2048e3286f34: "drm: rockchip: Add basic drm driver" from
Aug 22, 2014, leads to the following static checker warning:
drivers/gpu/drm/rockchip/rockchip_drm_vop.c:1383 vop_bind()
warn: unsigned 'vop->irq' is never less than zero.
drivers/gpu/drm/rockchip/rockchip_drm_vop.c
1381
1382 vop->irq = platform_get_irq(pdev, 0);
1383 if (vop->irq < 0) {
^^^^^^^^^^^^
Doesn't work.
1384 dev_err(dev, "cannot find irq for vop\n");
1385 return vop->irq;
1386 }
1387
drivers/gpu/drm/rockchip/rockchip_drm_vop.c:1188 vop_create_crtc()
warn: missing error code here? 'of_get_child_by_name()' failed.
1184 port = of_get_child_by_name(dev->of_node, "port");
1185 if (!port) {
1186 DRM_ERROR("no port node found in %s\n",
1187 dev->of_node->full_name);
Probably, "ret = -ENODEV;"
1188 goto err_cleanup_crtc;
1189 }
1190
regards,
dan carpenter
