Fixes the following W=1 kernel build warning(s): drivers/gpu/drm/vkms/vkms_drv.c:55:19: warning: variable ‘crtc’ set but not used [-Wunused-but-set-variable] 55 | struct drm_crtc *crtc; | ^~~~ Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Rob Clark <robdclark@gmail.com> Cc: dri-devel@lists.freedesktop.org Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20201112190039.2785914-3-lee.jones@linaro.org
