A good example to look at as a reference is the v4l2-pci-skeleton.c
-source that is available in this directory. It is a skeleton driver for
+source that is available in samples/v4l/. It is a skeleton driver for
a PCI capture card, and demonstrates how to use the V4L2 driver
framework. It can be used as a template for real PCI video capture driver.

With the new autoksyms support, we can run into a situation where the v4l pci skeleton module is the only one using some exported symbols that get dropped because they are never referenced by the kernel otherwise, causing a build problem: ERROR: "vb2_dma_contig_memops" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!

Specifically, we do look in the samples directory for users of symbols, but not the Documentation directory. This solves the build problem by moving the connector sample into the same directory as the other samples.
