Insufficient patch description.

Patch mangled.  Read Documentation/email-clients.txt send it to
yourself, verify that it applies with `git am`.

We introduced a lot of new functions here so it's not just a one to
one translation from the old strict_strtoul().  For example
kstrtou8() might be more appropriate here because that's what gets
passed to enable_oled().  You would need to change the type for
value as well.

Althought it doesn't matter much.  If the user passes anything
besides 1 or 0, they deserve what they get I suppose.

Preserve the error code instead of returning -EINVAL for everything.
