I did turn on treating warnings as error.

Hi,
just sending the original Niranjana's patch as an RFC. It's v3 as
the v2 has been reviewed offline with Ramalingam.
I'm still keeping most of the structure even though some further
discussion can be done starting from here.
Copy pasting Niranjana's original cover letter message:
Clean up punctuation, spelling, and formatting for command line usage
and modprobe config file usage in udlfb.rst.

The idea is to let vfio core manage the vfio_device life cycle instead
