drm/vc4: v3d: called object '0u' is not a function (next-20160104)

[Stefan Wahren]

Hi Eric,

i tried to build Linux next-20160104, but vc4 failed with the following
messages:

...
  CC      drivers/gpu/drm/vc4/vc4_v3d.o
drivers/gpu/drm/vc4/vc4_v3d.c: In function 'vc4_v3d_set_power':

make[3]: *** [drivers/gpu/drm/vc4] Error 2
make[2]: *** [drivers/gpu/drm] Error 2
make[1]: *** [drivers/gpu] Error 2
make: *** [drivers] Error 2

Here the relevant settings:

CONFIG_DRM_VC4=y
CONFIG_PM_SLEEP=n

It looks like pm_generic_poweroff and pm_generic_resume aren't used as intended.
They could be NULL.

Regards
Stefan
