Hi all,

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

drivers/gpu/drm/vc4/vc4_drv.c: In function 'vc4_drm_unbind':
drivers/gpu/drm/vc4/vc4_drv.c:322:18: warning: unused variable 'vc4' [-Wunused-variable]
  322 |  struct vc4_dev *vc4 = to_vc4_dev(drm);
      |                  ^~~

Introduced by commit

  dcda7c28bff2 ("drm/vc4: kms: Add functions to create the state objects")

Hi all,

This should have been reported against the vfs-fixes tree, sorry.
