The omap media driver can be built-in while the v4l2 core is a loadable module. This is a mistake and leads to link errors: drivers/media/platform/omap/omap_vout.o: In function `omap_vout_remove': omap_vout.c:(.text+0xec): undefined reference to `v4l2_device_unregister' omap_vout.c:(.text+0x140): undefined reference to `video_device_release' omap_vout.c:(.text+0x150): undefined reference to `video_unregister_device' omap_vout.c:(.text+0x15c): undefined reference to `v4l2_ctrl_handler_free' An explicit Kconfig dependency on VIDEO_V4L2 avoids the problem. I ran into this problem for the first time today during my randconfig builds, but could not find what caused it.
