 # P2-misc-daemon-fixes.patch
 #
 # Various daemon error handling and robustness fixes:
-# graceful degradation when audio hardware is absent, InputProducer migration
-# for USB HID, zerod argument handling and request loop resilience.
+# graceful degradation when audio hardware is absent,
+# zerod argument handling and request loop resilience.
 #
 # Covers:
 #   - audiod/main.rs: handle ENODEV when no audio hardware present
-#   - usbhidd/main.rs: migrate ProducerHandle→InputProducer with named producer
 #   - zerod/main.rs: derive Copy for Ty, graceful argument parsing, resilient request loop
 #
