Yeah. If this were a brand new driver then returning -EINVAL would be a
good idea.
Smatch actually warns about this code as well if you turn on the
--spammy option. But there are too many of these kinds of warnings and
even I can't check them all so the warning is basically useless.
In a few months I will have improved the Smatch code to know that the
source string is too large so this bug could have been avoided.
regards,
dan carpenter
