    And roll them out across drm_* files. The point here isn't code
    prettification (it helps with that too) but that some of these lists
    aren't static any more. And having macros will gives us a convenient
    place to put locking checks into.
    
    I didn't add an iterator for props since that's only used by a
    list_for_each_entry_safe in the driver teardown code.
    
    Search&replace was done with the below cocci spatch. Note that there's
    a bunch more places that didn't match and which would need some manual
    changes, but I've intentially left these out for this mostly automated
    patch.

    struct drm_crtc *crtc;
    struct drm_device *dev;
    expression head;

    - list_for_each_entry(crtc, &dev->mode_config.crtc_list, head) {
    + drm_for_each_crtc (crtc, dev) {
    ...
