I agree this to be reverted. (And the problem is bigger than lockdep,
and apparently not limited to suspend).

But we merged hacky solution because we wanted something simple for
stable, and I don't think that was good idea. (And I'm not sure this
is worth fixing in stable, as we don't have reports of people hitting
that in that kernels).

Best regards,
