[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

./mesh/crypto.c: In function ‘mesh_crypto_device_key’:
./mesh/crypto.c:436:33: error: initializer-string for array of ‘unsigned char’ truncates NUL terminator but destination lacks ‘nonstring’ attribute (5 chars into 4 available) [-Werror=unterminated-string-initialization]
  436 |         const uint8_t prdk[4] = "prdk";
      |                                 ^~~~~~
