   4 Subject: [PATCH 383/454] staging: vc04_services: move client dbg directory
   5  into static variable
   6
   7 commit 24e8d3fc42f25936ff270e404847a3a462c38468 upstream
   8
   9 This does not need to be part of a wrapper function, or in a structure,
  10 just properly reference it directly as a single variable.
  11
  12 The whole variable will be going away soon anyway, this is just a step
  13 toward that direction.
