Looks like this didn't catch the double assignments in:

drivers/media/platform/rcar_fdp1.c:     fdp1->irq = ret =
platform_get_irq(pdev, 0);
drivers/media/platform/rcar_fdp1.c-     if (ret < 0) {
drivers/media/platform/rcar_fdp1.c-             dev_err(&pdev->dev,
"cannot find IRQ\n");
drivers/media/platform/rcar_fdp1.c-             return ret;
drivers/media/platform/rcar_fdp1.c-     }
drivers/media/platform/rcar_fdp1.c-
--
drivers/media/platform/rcar_jpu.c:      jpu->irq = ret =
platform_get_irq(pdev, 0);
drivers/media/platform/rcar_jpu.c-      if (ret < 0) {
drivers/media/platform/rcar_jpu.c-              dev_err(&pdev->dev,
"cannot find IRQ\n");
drivers/media/platform/rcar_jpu.c-              return ret;
drivers/media/platform/rcar_jpu.c-      }
drivers/media/platform/rcar_jpu.c-

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
