    [PATCH] Driver Core: remove driver model detach_state · 0b405a0f
    David Brownell authored
    
    
    The driver model has a "detach_state" mechanism that:
    
     - Has never been used by any in-kernel drive;
     - Is superfluous, since driver remove() methods can do the same thing;
     - Became buggy when the suspend() parameter changed semantics and type;
     - Could self-deadlock when called from certain suspend contexts;
     - Is effectively wasted documentation, object code, and headspace.
    
    This removes that "detach_state" mechanism; net code shrink, as well
    as a per-device saving in the driver model and sysfs.
