Subject: 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/staging/vboxvideo/vbox_drv.c:235:2: error: unknown field 'set_busid' specified in initializer
  .set_busid = drm_pci_set_busid,
  ^
drivers/staging/vboxvideo/vbox_drv.c:235:15: error: 'drm_pci_set_busid' undeclared here (not in a function)
  .set_busid = drm_pci_set_busid,
               ^
drivers/staging/vboxvideo/vbox_drv.c: In function 'vbox_init':
drivers/staging/vboxvideo/vbox_drv.c:273:9: error: implicit declaration of function 'drm_pci_init' [-Werror=implicit-function-declaration]
  return drm_pci_init(&driver, &vbox_pci_driver);
         ^
drivers/staging/vboxvideo/vbox_drv.c: In function 'vbox_exit':
drivers/staging/vboxvideo/vbox_drv.c:278:2: error: implicit declaration of function 'drm_pci_exit' [-Werror=implicit-function-declaration]
  drm_pci_exit(&driver, &vbox_pci_driver);
  ^

Caused by commits

  5c484cee7ef9 ("drm: Remove drm_driver->set_busid hook")
  10631d724def ("drm/pci: Deprecate drm_pci_init/exit completely")

interacting with commit

  dd55d44f4084 ("staging: vboxvideo: Add vboxvideo to drivers/staging")

from the staging.current tree.

I have applied the following merge fix patch - please check that it
is correct.
