We get 2 warnings when building kernel with W=1: drivers/gpu/drm/nouveau/nouveau_display.c:96:1: warning: no previous prototype for 'nouveau_display_scanoutpos_head' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nv10_fence.c:70:1: warning: no previous prototype for 'nv10_fence_context_new' [-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'.
