We get 1 warning when building kernel with W=1: drivers/gpu/drm/tilcdc/tilcdc_drv.c:64:5: warning: no previous prototype for 'tilcdc_atomic_check' [-Wmissing-prototypes] In fact, this function is only used in the file in which it is declared and don't need a declaration, but can be made static. So this patch marks it 'static'.
