      HID: debug: fix race condition with between rdesc_show() and device removal · cef0d494
      He, Bo authored
      There is a race condition that could happen if hid_debug_rdesc_show()
      is running while hdev is in the process of going away (device removal,
      system suspend, etc) which could result in NULL pointer dereference:

      Grab driver_input_lock to make sure the input device exists throughout the

      HID: logitech: check the return value of create_singlethread_workqueue · 6c44b15e
      Kangjie Lu authored
      create_singlethread_workqueue may fail and return NULL. The fix checks if it is
      NULL to avoid NULL pointer dereference.  Also, the fix moves the call of
      create_singlethread_workqueue earlier to avoid resource-release issues.
