  driver core: take parent lock in async device attach (2026-10-16 22:36:09 +0200)

----------------------------------------------------------------
Driver core fixes for 7.4-rc1

- Make parent-lock requirements per device type instead of per bus,
  fixing a use-after-free on USB disconnect by limiting the requirement
  to USB interfaces, which retain a reference to their parent

- Honor parent-lock requirements during deferred and asynchronous
  probing, fixing USB interface probe races, including duplicate
  endpoint creation attempts in sysfs
