linux-next: build warning after merge of the drm tree

[Stephen Rothwell]

Hi all,

After merging the drm tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

drivers/gpu/drm/i915/gvt/cmd_parser.c: In function 'perform_bb_shadow':
drivers/gpu/drm/i915/gvt/cmd_parser.c:1647:8: warning: unused variable 'dst' [-Wunused-variable]
  void *dst = NULL;
        ^

Introduced by commit

  93588e545a4f ("Merge tag 'drm-intel-next-2017-11-17-1' of git://anongit.freedesktop.org/drm/drm-intel into drm-next")

this merge reintroduced the variable declaration removed by commit

  f52c380a48f5 ("drm/i915/gvt: Refine shadow batch buffer")
