[PATCH] powerpc: powernv: Fix build error on const discarding

Show all headers | View raw

When building a random powerpc kernel I hit this build error:
  CC      arch/powerpc/platforms/powernv/opal-imc.o
arch/powerpc/platforms/powernv/opal-imc.c: In function « disable_nest_pmu_counters »:
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 patch simply add const to l_cpumask to fix this issue.
