When building with clang, with CONFIG_OF unset, I got the following
error:
drivers/gpu/drm/sysfb/simpledrm.c:247:33: error: unused function
'simpledrm_device_of_dev' [-Werror,-Wunused-function]
247 | static struct simpledrm_device *simpledrm_device_of_dev(struct
drm_device *dev)
Add #if to define the function only when needed.
