Convert fb-helper, or at least the two code-paths which potentially trigger more than a single update, to use atomic API if the driver supports it.
The first patch is slightly unrelated, but I needed to add kerneldoc for 'struct drm_fb_helper' before I could add kerneldoc for the new atomic field. Danvet tricked me into writing some kerneldoc that way.
In theory, after this, we can re-introduce the ww_acquire_fini() call.
