Yeah, I had added --force to the help text
then removed it before sending, so I suppose
adding a warning there is OK too.

Nobody reads the --help text anyway.

Dan/Andrew/Greg?  You got a preference?

Maybe some help/warning text like:

  --force                    Without --force, checkpatch will not scan files
                             using -f or --file outside of drivers/staging/...
                             Do not use this option merely to create potential
                             patches that are uncompiled or untested.
