I prefer the following variant:
"0 on success or a negative error code on failure."
Then we do not use the overloaded "errno" name.
At least in include/drm/* my preferred variant is the most popular for
what it is worth.
OK, I'll change it to that.

Looks like some macro gone wrong - but I looked it up.
It is kernel-doc syntax for a named constant.
My personal preference would be a plain "0" - but that just
bikeshedding.
Yeah, I would prefer to use kernel-doc notation for constants.
It is documented and has been around for a long time.
I will resend the patch.
Thanks.
