Only the delayed-work fix needs an API added in v6.10. The devm port-status IRQ queues port_reset_war_work and plc_reset_work. disable_delayed_work_sync() rejects a later queue. The PHY notifier queues usb_role_sw_work and is not devres-managed. Unregister it, then keep cancel_work_sync(). That applies below v6.10. Changes in v2: - Split the Fixes tags. Only patch 2/2 is marked # 6.10+. - Keep each Fixes tag on one line. (Thierry Reding) - Disable plc_reset_work too. The port-status IRQ can requeue it. (Thierry Reding) - Unregister the VBUS notifier before draining usb_role_sw_work.
