      USB: serial: option: add support for Foxconn T77W968 LTE modules · f0797095
      Aleksander Morgado authored
      These are the Foxconn-branded variants of the Dell DW5821e modules,
      same USB layout as those. The device exposes AT, NMEA and DIAG ports
      in both USB configurations.

      usbip: Fix uninitialized symbol 'nents' in stub_recv_cmd_submit() · 2a912531
      Suwan Kim authored
      Smatch reported that nents is not initialized and used in
      stub_recv_cmd_submit(). nents is currently initialized by sgl_alloc()
      and used to allocate multiple URBs when host controller doesn't
      support scatter-gather DMA. The use of uninitialized nents means that
      buf_len is zero and use_sg is true. But buffer length should not be
      zero when an URB uses scatter-gather DMA.
      
      To prevent this situation, add the conditional that checks buf_len
      and use_sg. And move the use of nents right after the sgl_alloc() to
      avoid the use of uninitialized nents.
      
      If the error occurs, it adds SDEV_EVENT_ERROR_MALLOC and stub_priv
      will be released by stub event handler and connection will be shut
      down.
