Hi all,

After merging the drm-misc tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/gpu/drm/nouveau/nouveau_drm.c: In function 'nouveau_drm_probe':
drivers/gpu/drm/nouveau/nouveau_drm.c:797:17: error: implicit declaration of function 'drm_fbdev_generic_setup' [-Werror=implicit-function-declaration]
  797 |                 drm_fbdev_generic_setup(drm_dev, 8);
      |                 ^~~~~~~~~~~~~~~~~~~~~~~

Caused by commit

  8ab59da26bc0 ("drm/fb-helper: Move generic fbdev emulation into separate source file")

interacting with commit

  4a16dd9d18a0 ("drm/nouveau/kms: switch to drm fbdev helpers")

from the drm tree.

I have applied the following merge fix patch for today.
