From cacaeb0c23979d20652d862e8ff974d9d7244e2d Mon Sep 17 00:00:00 2001 From: Wang Wensheng Date: Wed, 23 Sep 2020 07:14:53 +0000 Subject: [PATCH] powerpc/perf: Fix symbol undeclared warning Build kernel with `C=2`: arch/powerpc/perf/isa207-common.c:24:18: warning: symbol 'isa207_pmu_format_attr' was not declared. Should it be static? arch/powerpc/perf/power9-pmu.c:101:5: warning: symbol 'p9_dd21_bl_ev' was not declared. Should it be static? arch/powerpc/perf/power9-pmu.c:115:5: warning: symbol 'p9_dd22_bl_ev' was not declared. Should it be static? Those symbols are used only in the files that define them so we declare them as static to fix the warnings.
