ACPI: NUMA: Remove the useless sub table pointer check
In acpi_parse_entries_array(), the subtable entries (entry.hdr) will never be NULL, so for ACPI subtable handler in struct acpi_subtable_proc, will never handle NULL subtable entries. Remove those useless subtable pointer checks in the callback handlers. Signed-off-by: Hanjun Guo <guohanjun@huawei.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
