Subject: [PATCH] PCI: Release OF node in pci_scan_device()'s error path
Git-commit: c99e755a4a4c165cad6effb39faffd0f3377c02d
Patch-mainline: v5.13-rc1
References: git-fixes

In pci_scan_device(), if pci_setup_device() fails for any reason, the code
will not release device's of_node by calling pci_release_of_node().  Fix
that by calling the release function.

Fixes: 98d9f30c820d ("pci/of: Match PCI devices to OF nodes dynamically")
