people having the fbcon-locking-fixes [1] in their local GIT tree can
revert this change?
Yeah, if you have all the fixes reverting this is fine and appreciated
to increase testing. Dave will probably push the revert himself to
drm-next soon.

The revert is now in -rc6.
Hmmm, I have here...
CONFIG_LOCKDEP_SUPPORT=y
Excerpts from the revert [1]:

I would have expected a check for CONFIG_LOCKDEP_SUPPORT.
This is BTW with Linux v3.8-rc5!

Revert "console: implement lockdep support for console_lock"
This reverts commit daee779718a319ff9f83e1ba3339334ac650bb22.
I'll requeue this after the console locking fixes, so lockdep
is useful again for people until fbcon is fixed.

Thanks!
