[PATCH -next] PCI: tegra: Fix the error return code in tegra_pcie_dw_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Fix the error return code in tegra_pcie_dw_probe() by using error code
instead of PTR_ERR(NULL) which is always 0.

Fixes: 6404441c8e13 ("PCI: tegra: Add Tegra194 PCIe support")
