drivers/gpu/drm/qxl/qxl_cmd.c:424:6: error: variable 'count' set but not used

[Miguel Ojeda]

Hi,

In today's next, I got:

    drivers/gpu/drm/qxl/qxl_cmd.c:424:6: error: variable 'count' set
but not used [-Werror,-Wunused-but-set-variable]

`count` seems to be there since commit f64122c1f6ad ("drm: add new QXL
driver. (v1.4)").

Untested diff below -- if you want a formal patch, please let me know.

Cheers,
Miguel
