Hello Chen-Yu Tsai,

Commit 1a152e21940a ("PCI: mediatek-gen3: Integrate new pwrctrl API")
from Mar 24, 2026 (linux-next), leads to the following Smatch static
checker warning:

	drivers/pci/controller/pcie-mediatek-gen3.c:1226 mtk_pcie_probe()
	warn: ignoring unreachable code.

drivers/pci/controller/pcie-mediatek-gen3.c
    1202 static int mtk_pcie_probe(struct platform_device *pdev)
    1203 {
    1204         struct device *dev = &pdev->dev;
    1205         struct mtk_gen3_pcie *pcie;
    1206         struct pci_host_bridge *host;
    1207         int err;
    1208 
    1209         host = devm_pci_alloc_host_bridge(dev, sizeof(*pcie));
    1210         if (!host)
    1211                 return -ENOMEM;
    1212 
    1213         pcie = pci_host_bridge_priv(host);
    1214 
    1215         pcie->dev = dev;
    1216         pcie->soc = device_get_match_data(dev);
    1217         platform_set_drvdata(pdev, pcie);
    1218 
    1219         err = mtk_pcie_setup_irq(pcie);
    1220         if (err)
    1221                 return dev_err_probe(dev, err, "Failed to setup IRQ domains\n");
    1222

--> 1226                 dev_err_probe(dev, err, "failed to create pwrctrl devices\n");

The error message is unreachable.
