Subject: [PATCH v4 4/9] PCI: imx6: Correct controller_id generation logic for i.MX7D
Date: Tue, 15 Oct 2024 16:33:28 +0800 [thread overview]
Message-ID: <1728981213-8771-5-git-send-email-hongxing.zhu@nxp.com> (raw)
In-Reply-To: <1728981213-8771-1-git-send-email-hongxing.zhu@nxp.com>
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.
