linux-next: build failure after merge of the drm-misc tree

Hi all,

After merging the drm-misc tree, today's linux-next build (x86_64 allmodconfig) failed like this:

drivers/gpu/drm/virtio/virtgpu_drm_bus.c: In function 'virtio_pci_kick_out_firmware_fb': drivers/gpu/drm/virtio/virtgpu_drm_bus.c:55:2: error: implicit declaration of function 'drm_fb_helper_remove_conflicting_framebuffers' [-Werror=implicit-function-declaration] drm_fb_helper_remove_conflicting_framebuffers(ap, "virtiodrmfb", ^

Caused by commit

7bd870e7b1c8 ("drm/virtio: Use new drm_fb_helper functions")

I have used the drm-misc tree from next-20150713 for today.

(That commit said "COMPILE TESTED ONLY" :-()
