We get 5 warnings when building kernel with W=1: drivers/gpu/drm/nouveau/nvkm/engine/disp/rootnv50.c:70:1: warning: no previous prototype for 'nv50_disp_root_mthd_' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/engine/disp/channv50.c:157:1: warning: no previous prototype for 'nv50_disp_chan_rd32' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/engine/disp/channv50.c:167:1: warning: no previous prototype for 'nv50_disp_chan_wr32' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/engine/disp/channv50.c:177:1: warning: no previous prototype for 'nv50_disp_chan_ntfy' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/engine/disp/channv50.c:193:1: warning: no previous prototype for 'nv50_disp_chan_map' [-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'.
