Alex James 4e6cbe5689 ACPICA: iASL: Ensure that the target node is valid in acpi_ex_create_alias 
ACPICA commit 8b14afac65d983610cc5387ede6d85ea5ee075be

The following ACPI table contains an invalid target node within the
Alias operator:

definition_block ("", "SSDT", 1, "Bug", "BugTable", 0x00001000)
{
    Scope (_SB)
    {
        Device (DEV0)
        {
            Name (_ADR, 1)

            Device (DEV1)
            {
                Alias (_ADR, _ADR)
            }
        }
    }
}

If an ACPI table contains such an invalid target node in an Alias
operator, a segmentation fault will occur when the target node is
dereferenced within acpi_ex_create_alias. Add a check for such an invalid
target node in acpi_ex_create_alias and return AE_NULL_OBJECT as suggested
by @acpibob.
