> 
> Move the flip_pending assignment into __intel_fbc_post_update() from
> intel_fbc_post_update(). Now mirrors the pre_update() side.
> 
> The only reason the assignment was in the higher level function is that we used
> to call __intel_fbc_post_update() from elsewhere as well. That got cleaned up in
> commit b39d2c620242 ("drm/i915/fbc:
> Call intel_fbc_activate() directly from frontbuffer flush")
