[Spice-devel] [PATCH] drm/qxl: drop set_prod_notify parameter from qxl_ring_create

[Zongmin Zhou]

Since qxl_io_reset(qdev) will be called immediately
after qxl_ring_create() been called,
and parameter like notify_on_prod will be set to default value.
So the call to qxl_ring_init_hdr() before becomes meaningless.
