[PATCH v1 4/9] PCI: imx6: Correct controller_id generation logic for i.MX7D
Posted by Richard Zhu 2 months ago
i.MX7D only has one PCIe controller, so controller_id should always be 0.
The previous code is incorrect although yielding the correct result.
Fix by removing IMX7D from the switch case branch.
