[Intel-gfx] [PATCH 05/14] drm/atomic: trim driver interface/docs
Daniel Vetter
daniel.vetter at ffwll.ch
Mon Sep 3 16:54:30 UTC 2018
Remove the kerneldoc and EXPORT_SYMBOL which aren't used and really
shouldn't ever be used by drivers directly.
Unfortunately this means we need to move the set_writeback_fb function
around to avoid a forward decl.
