Subject: [PATCH] powerpc/powernv: Fix build error in opal-imc.c when NUMA=n
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Patch-mainline: v4.14-rc1
Git-commit: 6538ac30841638b2fd345725a9fd155c6fe1768a
When building a random powerpc kernel I hit this build error:
arch/powerpc/platforms/powernv/opal-imc.c:130:13: error : assignment
discards « const » qualifier from pointer target type
[-Werror=discarded-qualifiers]
l_cpumask = cpumask_of_node(nid);
^
This happens because when CONFIG_NUMA=n cpumask_of_node() returns a
const pointer.
This patch simply adds const to l_cpumask to fix this issue.
