__WARN() cannot be used in portable code, since it is only available on some architectures and configurations: drivers/media/platform/pxa_camera.c: In function 'pxa_mbus_config_compatible': drivers/media/platform/pxa_camera.c:642:3: error: implicit declaration of function '__WARN'; did you mean '__WALL'?
