We get 4 warnings when building kernel with W=1: drivers/gpu/drm/tilcdc/tilcdc_tfp410.c:393:12: warning: no previous prototype for 'tilcdc_tfp410_init' [-Wmissing-prototypes] drivers/gpu/drm/tilcdc/tilcdc_tfp410.c:398:13: warning: no previous prototype for 'tilcdc_tfp410_fini' [-Wmissing-prototypes] drivers/gpu/drm/tilcdc/tilcdc_panel.c:443:12: warning: no previous prototype for 'tilcdc_panel_init' [-Wmissing-prototypes] drivers/gpu/drm/tilcdc/tilcdc_panel.c:448:13: warning: no previous prototype for 'tilcdc_panel_fini' [-Wmissing-prototypes] In fact, these functions are declared in drivers/gpu/drm/tilcdc/tilcdc_tfp410.h, drivers/gpu/drm/tilcdc/tilcdc_panel.h, so this patch adds missing header dependencies.
