Subject: [PATCH 0/2] fbcon+i915 locking fixes

Hi Dave,

First patch is a resend of Alan's fbcon vs. fb notifier deadlock fix.
Without this lockdep is pretty much useless for debugging drm locking
issues, and it looks like quite a few bootup hangs could be blamed on this
one, too.

Since the fbdev maintainer seems to be awol, please merge this through
your drm tree. I've looked through the patch and the new locking seems to
be sane so feel free to smash a

onto it.

2nd patch is a locking bug in the i915 driver with the new kms locking.
Since the bug only happens in your drm-next tree, please apply the patch
there directly.

Thanks, Daniel
