Hi Eric,
This pull request does not have the patch required to fix the build
failure for some architectures. Just checked Linus's current tree for
tilepro allmodconfig and it still fails to build. The error being:

drivers/gpu/drm/vc4/vc4_v3d.c: In function 'vc4_v3d_set_power':
include/linux/stddef.h:7:14: error: called object is not a function or function pointer
 #define NULL ((void *)0)
              ^
include/linux/pm.h:776:30: note: in expansion of macro 'NULL'
 #define pm_generic_poweroff  NULL
                              ^

   return pm_generic_poweroff(&vc4->v3d->pdev->dev);
          ^

   return pm_generic_resume(&vc4->v3d->pdev->dev);

patch is at:

Or:

https://lkml.org/lkml/2016/1/9/170

which retains the functionality if CONFIG_PM_SLEEP is configured.
