The Kconfig file for this module says:

config VIDEO_PCI_SKELETON
tristate "Skeleton PCI V4L2 driver"
depends on PCI && BUILD_DOCSRC
depends on VIDEO_V4L2 && VIDEOBUF2_CORE && VIDEOBUF2_MEMOPS

so it should already be limited to VIDEO_V4L2 being enabled.

What kernel or linux-next version did you see a problem with?

Please send the failing .config file so that I can check it.

Thanks.
