I wonder if VIDEO_V4L2_SUBDEV_API itself should depend on VIDEO_V4L2. That'd be logical, I don't think VIDEO_V4L2_SUBDEV_API could be meaningfully used with VIDEO_V4L2 disabled. The API implementation is in v4l2-subdev.c which itself depends on VIDEO_V4L2. Oddly enough, VIDEO_V4L2_SUBDEV_API is currently defined in drivers/media/Kconfig, it should probably be in drivers/media/v4l2-core/Kconfig instead. -- Kind regards, Sakari Ailus e-mail: sakari.ailus@xxxxxx XMPP: sailus@xxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
