   4 Subject: [PATCH 20/25] crypto: crypto4xx - fix various warnings
   5
   6 crypto4xx_core.c:179:6: warning: symbol 'crypto4xx_free_state_record'
   7         was not declared. Should it be static?
   8 crypto4xx_core.c:331:5: warning: symbol 'crypto4xx_get_n_gd'
   9         was not declared. Should it be static?
  10 crypto4xx_core.c:652:6: warning: symbol 'crypto4xx_return_pd'
  11         was not declared. Should it be static?
  12
  13 crypto4xx_return_pd() is not used by anything. Therefore it is removed.
