From 3873f16d4936690ddd7b35231fa5c712a3c63a54 Mon Sep 17 00:00:00 2001 From: Duoming Zhou Date: Wed, 17 Dec 2025 11:00:18 +0800 Subject: [PATCH] Input: psmouse - replace flush_workqueue() with disable_delayed_work_sync() The original code uses flush_workqueue() in psmouse_disconnect() to ensure the completion of both resync_work and dev3_register_work. Given that alps_disconnect() already uses disable_delayed_work_sync() to cancel dev3_register_work, replacing flush_workqueue() with disable_delayed_work_sync(&psmouse->resync_work) is more robust and efficient.
