We get 3 warnings when building kernel with W=1: drivers/gpu/drm/nouveau/nvkm/subdev/volt/gpio.c:35:1: warning: no previous prototype for 'nvkm_voltgpio_get' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/subdev/volt/gpio.c:54:1: warning: no previous prototype for 'nvkm_voltgpio_set' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/subdev/volt/gpio.c:71:1: warning: no previous prototype for 'nvkm_voltgpio_init' [-Wmissing-prototypes] In fact, these functions are declared in drivers/gpu/drm/nouveau/nvkm/subdev/volt/priv.h. So this patch adds missing header dependencies.
