- * DESCRIPTION: This function is called to place a package object in a user
- * buffer. A package object by definition contains other objects.
- *
- * The buffer is assumed to have sufficient space for the object.
- * The caller must have verified the buffer length needed using the
- * acpi_ut_get_object_size function before calling this function.
+ * DESCRIPTION: Copy an external package object to an internal package.
+ * Handles nested packages.
