This sample driver was originally under Documentation/ and was moved
to samples, but build support was never adjusted for the new location.

This change would bring this example driver in Kernel build system if
selected. I do have verified build and tested it on x86_64 platform.
Have you verified x86 and PPC/ARM build (which I think primarily could
use VFIO)?
Thanks,

I have not, but I'm fairly confident that CONFIG_SAMPLES is not a
typical user or distro config option, so I think we're at a low risk
of breaking anyone. In general I test almost exclusively for x86_64 and
rely on external auto builders to identify issues on other archs.
Thanks,

Ok. I'm fine with this change. Also saw Eric's confirmation on ARM
aarch64 compilations. Thanks.
