    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,
    Peter
