Jean-Francois Moine 739570bb21 V4L/DVB (8352): gspca: Buffers for USB exchanges cannot be in the stack. 
gspca:    Protect dq_callback() against simultaneous USB exchanges.
          Temporary buffer for USB exchanges added in the device struct.
(all)     Use a temporary buffer for all USB exchanges.
