Only theoretical ;)
Since all other drivers always lock around drm_helper_resume_force_mode I 
guessed this is good practice.

And since problem area is quite similar to the one mentioned in #927a2f119 / 
234f78a683e 
http://git.kernel.org/?p=linux/kernel/git/stable/linux-
stable.git;a=commit;h=234f78a683e30d6d4628846fde4a822c0e385529
the bug might happen in the wild.


Thanks,
