drm/i810: make i810_flush_queue() return void
This function always return '0' and no callers use the return value. So make it a void function. This eliminates the following coccicheck warning: drivers/gpu/drm/i810/i810_dma.c:860:8-11: Unneeded variable: "ret". Return "0" on line 885 Reported-by: Hulk Robot <hulkci@huawei.com> Signed-off-by: Jason Yan <yanaijie@huawei.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20200910140610.1191578-1-yanaijie@huawei.com
