It would have been helpful if you had communicated that, I explicitly
asked Alex which tree he'd prefer merging through. If you're his
stand-in then why didn't you reply?
I was already wondering why you took the time to reply to Daniel's patch
(which went into drm-misc-next, so queued for 4.13), but didn't reply
at all to my patch (which affects 4.12, so arguably has higher priority).
I'd dispute that the issue at hand requires specific domain knowlege,
it's a trivial dereference of a pointer before it's set.

End of the week means the patch would miss another rc cycle, and the
DRM subsystem is getting enough criticism for causing regressions as
it is, isn't it? :-(
Thanks,
Lukas
