Subject: [PATCH] virtio: pci: Fix an error handling path in vp_modern_probe()
Git-commit: 7a836a2aba09479c8e71fa43249eecc4af945f61
Patch-mainline: v5.19-rc1
References: git-fixes
If an error occurs after a successful pci_request_selected_regions() call,
it should be undone by a corresponding pci_release_selected_regions() call,
as already done in vp_modern_remove().
Fixes: fd502729fbbf ("virtio-pci: introduce modern device module")
