   4 Subject: [PATCH] scripts/dtc: Fix UMR causing corrupt dtbo overlay files
   5
   6 struct fixup_entry is allocated from the heap but it's member
   7 local_fixup_generated was never initialized. This lead to
   8 corrupted dtbo files.
   9
  10 Fix this by initializing local_fixup_generated to false.
