   4 Subject: [PATCH] staging: vc04_services: isp: Remove duplicated
   5  initialisation
   6
   7 With the codec code from which this was derived, the driver had to
   8 get the supported formats for both input and output ports.
   9 This had been copied across, however here we have independent nodes
  10 for each port, but the code had been left in to do the same thing
  11 twice.
  12 Remove the duplicate.
