Hello Daniel Mack,
The patch a9b47c7f2390: "video: pxa3xx-gcu: switch to devres
functions" from Mar 5, 2014, leads to the following static checker
warning:
drivers/video/fbdev/pxa3xx-gcu.c:616 pxa3xx_gcu_probe()
warn: 'priv->mmio_base' isn't an ERR_PTR
drivers/video/fbdev/pxa3xx-gcu.c
612
613 /* handle IO resources */
614 r = platform_get_resource(pdev, IORESOURCE_MEM, 0);
615 priv->mmio_base = devm_request_and_ioremap(dev, r);
616 if (IS_ERR(priv->mmio_base)) {
devm_request_and_ioremap() returns NULL on error.
617 dev_err(dev, "failed to map I/O memory\n");
618 return PTR_ERR(priv->mmio_base);
619 }
