Hi Greg,

Upstream commit a0040c014594 ("ACPI / PCI: Bail early in 
acpi_pci_add_bus() if there is no ACPI handle ").

This patch fixes a NULL pointer access when ACPI_HANDLE() is NULL.
acpi_evaluate_dsm() fails as follows while there is no DSM in the tables.

ACPI: \: failed to evaluate _DSM (0x1001)
