drm/nouveau/fbcon: fix oops without fbdev emulation
[ Upstream commit
4813766325374af6ed0b66879ba6a0bbb05c83b6 ]
This is similar to an earlier commit
52dfcc5ccfbb ("drm/nouveau: fix for
disabled fbdev emulation"), but protects all occurrences of helper.fbdev
in the source.
I see oops in nouveau_fbcon_accel_save_disable() called from
nouveau_fbcon_set_suspend_work() on Linux 3.13 when
CONFIG_DRM_FBDEV_EMULATION option is disabled.
