In my reading I failed to catch the how transient 'staging' is--I'll
keep it mind, as I'm hoping my driver will not be so transient.

This would then necessitate maintaining both chunks of code, so I think
for now I will develop my module in drivers/misc. After it has stabilized,
I can add both modules to IIO as well with this in mind.
