I'm using an OpenEmbedded variant, Poky They are not created on boot but when i modprobe omap3-isp (and tvp5150 gets automatically loaded). Udev is version 173 and i'm using Angstrom, an OpenEmbedded (core) variant too. Anyway when developing the patch it happened to me too that i had those subdev open errors, but if i remember correctly only for tvp5150 so it was something wrong in my code. And if i continue to remember correctly it was because you had to set the V4L2_SUBDEV_FL_HAS_DEVNODE after calling v4l2_i2c_subdev_init. Seems nonsense but this is what i remember, actually this is what the mt9v032 driver does.
