Subject: [PATCH] event/dpaa: fix integer overflow of max ports
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[ upstream commit 100915c0a51121fdbbb3be04aa73823f54e20cda ]

dev_info->max_event_ports is uint8_t. dpaa_event_dev_info_get assigns
DPAA_EVENT_MAX_EVENT_PORT (which is RTE_MAX_LCORE, upto 256 in ppc64le)
into this variable, which breaks compile in ppc64le.

drivers/event/dpaa/dpaa_eventdev.c: In function ‘dpaa_event_dev_info_get’:
   rte_config.h:23:23: error:
   large integer implicitly truncated to unsigned type [-Werror=overflow]
      #define RTE_MAX_LCORE 256

Fixes: 9caac5dd1e ("event/dpaa: introduce PMD")
