Absolutely. In fact, it's a pet pieve of mine. Lots and lots
of clueless driver writes return -EINVAL in such cases,
and I keep cleaning it up. The problem with EINVAL is that
it makes it harder to diagnose any problems that can come up.

Also, recent strerror() returns "Inappropriate ioctl for a device",
if that is your concern. Personally, I think "Not a typewriter"
was a warmer and fuzzier reference to the roots, but oh well...
