Fixing the return codes is a good idea but it won't fix the oops.
What's the point of returning 1 and 0? In the current code no one
cares and both are treated the same.
Also if we decide to fix this instead of reverting the we could do this
cleanup as well:
diff --git a/drivers/hid/hid-core.c b/drivers/hid/hid-core.c
index b8470b1..868ebaa 100644
