[dpdk-dev] [PATCH v2 3/4] cryptodev: fix the clang compiling issue

[Gavin Hu]

~/dpdk/lib/librte_eventdev/rte_event_crypto_adapter.c:530:49: error:
'rte_memcpy' call operates on objects of type 'struct rte_event'
while the size is based on a different type
      'struct rte_event *' [-Werror,-Wsizeof-pointer-memaccess]
                rte_memcpy(ev, &m_data->response_info, sizeof(ev));
~/arm_repo/dpdk/lib/librte_eventdev/rte_event_crypto_adapter.c:530:49:
note: did you mean to dereference the argument to 'sizeof' (and multiply
it by the number of elements)?
      rte_memcpy(ev, &m_data->response_info, sizeof(ev));
