[PATCH 0/2] Input: alps/psmouse: Fix UAF bugs and improve workqueue synchronization

[Duoming Zhou <duoming@zju.edu.cn>]

This patch series addresses use-after-free bugs in the ALPS
touchpad driver and enhances workqueue handling efficiency
in the psmouse subsystem.

The first patch fixes a critical use-after-free race condition
in the ALPS driver where dev3_register_work could be scheduled
after the alps_data structure was already freed. This was caused
by insufficient synchronization during device disconnection,
where flush_workqueue() couldn't prevent subsequent work item
submissions.

The second patch optimizes the psmouse disconnect path by replacing
flush_workqueue() with disable_delayed_work_sync() for better
efficiency and robustness.

Duoming Zhou (2):
  Input: alps - fix use-after-free bugs caused by dev3_register_work
  Input: psmouse - Replace flush_workqueue() with
    disable_delayed_work_sync()
