This doesn't work on top of v6.13-rc1. The alias symbol name has been
renamed by commit 054a9cd395a7 (modpost: rename alias
symbol for MODULE_DEVICE_TABLE())

I applied the following change to make it work again:
-            concat!("__mod_", $table_type,
+            concat!("__mod_device_table__", $table_type,
                     "__", module_path!(),
                     "_", line!(),
-                    "_", stringify!($table_name),
-                    "_device_table")
+                    "_", stringify!($table_name))
