      USB: serial: fix null-pointer dereferences on disconnect · b2ca6990
      Johan Hovold 提交于
      Make sure serial-driver dtr_rts is called with disc_mutex held after
      checking the disconnected flag.
      
      Due to a bug in the tty layer, dtr_rts may get called after a device has
      been disconnected and the tty-device unregistered. Some drivers have had
      individual checks for disconnect to make sure the disconnected interface
      was not accessed, but this should really be handled in usb-serial core
      (at least until the long-standing tty-bug has been fixed).
      
      Note that the problem has been made more acute with commit 0998d063
      ("device-core: Ensure drvdata = NULL when no driver is bound") as the
      port data is now also NULL when dtr_rts is called resulting in further
      oopses.
