What's the status of this one?

I'm assuming the fix is commit 721017cf4bd8 ("drm/i915/gem: Ignore
readonly failures when updating relics"), but didn't see a reply to
the query or a confirmation of things working..

Btw, Chris, that __put_user() not testing the error should at least
have a comment. We don't have a working "__must_check" for those
things (because they are subtle macros, not functions), but if we did,
we'd get a compiler warning for not checking the error value.
