commit 2b8be57fa0 upstream.
This reverts commit 631b2af2f3 ("PCI/ACPI: Fix allocated memory release
on error in pci_acpi_scan_root()").
The reverted patch causes the 'ri->cfg' and 'root_ops' resources to be
released multiple times.
When acpi_pci_root_create() fails, these resources have already been
released internally by the __acpi_pci_root_release_info() function.
Releasing them again in pci_acpi_scan_root() leads to incorrect behavior
and potential memory issues.
We plan to resolve the issue using a more appropriate fix.
