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)

Please always cc: the developers and maintainers of the patch you wish to have applied to a stable tree when asking to do so.
Can you resend this and do that?
thanks,

Place a NULL pointer check using the above mentioned code rather than let ACPI fail miserably.
