286 * The table_size is not the size of the complete ACPI table (the length
287 * field in the header struct), but only the size of the root table; i.e.,
288 * the offset from the very first byte of the complete ACPI table, to the

414 * @id: table id to find
417 * Scan the ACPI System Descriptor Table (STD) for a table matching @id,
420 * Return 0 if table found, -errno if not.
