[dpdk-dev] [PATCH] eal/ppc: fix rte_smp_mb for a compilation error with else clause

[Gowrishankar]

From: Gowrishankar Muthukrishnan <gowrishankar.m at linux.vnet.ibm.com>

This patch fixes the compilation problem with rte_smp_mb,
when there is else clause following it, as in test_barrier.c.

Fixes: 05c3fd7110 ("eal/ppc: atomic operations for IBM Power")
Cc: stable at dpdk.org
