[dpdk-dev] [PATCH v4 2/3] eventdev: fix the clang compiling issue

[Gavin Hu <gavin.hu@arm.com>]

From: gavin hu <gavin.hu@arm.com>

This patch fix the clang compiling issue reported on the ARM64
builing hosts. ev is a pointer in size of 64bit, but herein
it should be the size of its content.

~/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));

Fixes: 7901eac340 ("eventdev: add crypto adapter implementation")
