Subject: [PATCH AUTOSEL 4.19 281/671] drm/vmwgfx: Remove set but not used variable 'restart'

From: YueHaibing <yuehaibing@...wei.com>

[ Upstream commit b2130cca9c8db5073b71d832da2a6c8311a8f3bb ]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/vmwgfx/vmwgfx_cmdbuf.c: In function 'vmw_cmdbuf_work_func':
drivers/gpu/drm/vmwgfx/vmwgfx_cmdbuf.c:514:7: warning:
 variable 'restart' set but not used [-Wunused-but-set-variable]

It not used any more after commit dc366364c4ef ("drm/vmwgfx: Fix multiple
command buffer context use")
