drm_*_unreference() helpers.

This isn't an upstream tree (and the aspeed driver isn't in upstream
afaict), so no need for spamming mailing lists I think.

But thanks for doing all this, great motivation to put more of the drm
refactorings into cocci files.

Cheers, Daniel

Agreed.

Julia, I am happy getting a heads up about changes from the 0day bots,
but I would prefer not to spam others or the lists. If we can't
restrict the emails to just me then perhaps it's best to disable them
for github.com/shenki/linux.git.

FWIW, the aspeed gfx driver has been posted to dri-devel so it will be
upstream soon-ish.

Cheers,

Joel

Perhaps you can contact Fengguang about this? I just forward to whoever
the automatically generated message says to forward to. And I don't
always remember to include the information about the tree, which comes to
me in another message, so it can indeed be confusing.

Most welcome :)

thanks for feedback Daniel, we will mark this repo as private one to avoid
reporting to larger mailing list.
