We get 5 warnings when building kernel with W=1: drivers/gpu/drm/nouveau/nvkm/engine/gr/gf100.c:1388:1: warning: no previous prototype for 'gf100_gr_init_fw' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/engine/gr/gf100.c:1705:1: warning: no previous prototype for 'gf100_gr_init_' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/engine/gr/gm107.c:312:1: warning: no previous prototype for 'gm107_gr_init' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/engine/gr/ctxgf117.c:222:1: warning: no previous prototype for 'gf117_grctx_generate_main' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/engine/gr/ctxgm107.c:937:1: warning: no previous prototype for 'gm107_grctx_generate_tpcid' [-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'.
