I sort of prefer the original...
The hgsmi_query_conf() function returns negative error codes if it
can't complete the query because of allocation failures. To me that's
more obvious, when we write it in the original way.
In the new code it looks like it returns bool or something. The
copy_to/from_user() are normally written like if (copy_to_user()) {
but those don't return negative error codes so it's a different
situation.
This isn't something in checkpatch or CodingStyle so there isn't a
standard. It's just personal opinion vs personal opinion. If you were
going to do a lot of vboxvideo development, then it would be your
opinion which matters the most because you are doing the work. But
this is your first vboxvideo patch...
Let's just leave it as-is.
