+Subject: [PATCH] Amend use of `class_create()` for kernels >= 6.4
+
+The function signature for `class_create()` was changed in kernels >= 6.4.x to only accept a single argument (see kernel commit #dcfbb67).
+
+This change will conditionally modify how `class_create()` is called depending on the kernel version.
