[PATCH v2 07/13] PCI: apple: Fix missing OF node reference in apple_pcie_setup_port

From: Marc Zyngier
Date: Tue Mar 25 2025 - 06:28:21 EST


From: Hector Martin <marcan@xxxxxxxxx>

In the success path, we hang onto a reference to the node, so make sure
to grab one. The caller iterator puts our borrowed reference when we
return.
