From d1936cc2fc56f4cd7399b963fd66d58b539bb515 Mon Sep 17 00:00:00 2001 From: Baoyou Xie Date: Sat, 22 Oct 2016 16:48:26 +0800 Subject: [PATCH] drm/amdgpu: mark symbols static where possible MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We get 2 warnings when building kernel with W=1: drivers/gpu/drm/amd/amdgpu/si.c:908:5: warning: no previous prototype for 'si_pciep_rreg' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/si.c:921:6: warning: no previous prototype for 'si_pciep_wreg' [-Wmissing-prototypes] In fact, both functions are only used in the file in which they are declared and don't need a declaration, but can be made static. So this patch marks these functions with 'static'.
