   4 Subject: [PATCH 384/454] staging: vc04_services: remove struct
   5  vchiq_debugfs_info
   6
   7 commit 127892febb2d5d6612756da2d7d0bab526db3b51 upstream
   8
   9 This structure, and the one static variable that was declared with it,
  10 were not being used for anything.  The log_categories field was being
  11 set, but never used again.  So just remove it entirely as it is not
  12 needed at all.
