ACPI: Set length even for TYPE_END_TAG acpi resource
Found with a network device in QEMU/KVM guest not working anymore. Bisected to commit c13085e5 ACPICA: Resource Mgr: Prevent infinite loops in resource walks That commit will check acpi_resource length strictly which causes acpi_set_current_resources to return failure and IRQ for PCI devices is not set properly. Set length for all those TYPE_END_TAG acpi_resources. [rjw: Changelog] Bisected-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Rafael J.
