Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux

Pull console lockdep checking revert from Dave Airlie.

The lockdep splat this showed was interesting, but it's very very old,
and we won't be fixing it until 3.9.  In the meantime, undo the lockdep
annotation so that we don't generate the (known) console lockdep issue,
and then possibly hide any potential other (unknown) lockdep problems
that got disabled by the first one that triggered.

  Revert "console: implement lockdep support for console_lock"
