Yes, I agree. But for the typos, the user must get BAD_SIGN_OFF
warning for "Non-standard signature". So user will have to fix that
manually. If so, this error is already avoided.

For the release commits, I think the user(s) may not use checkpatch

For the rest (ie reverts) with no sign-offs, I think that if we just
add the sign off line, it serves our purpose.
Of course if we explain them to revert with sign-off, it will be
probably the same outcome.

Thus, I feel that we can proceed with this fix for this class of error.
What do you think/suggest?

Thanks
Aditya
