[Spice-devel] [PATCH qxl-win] miniport+display: export UPDATE_MEM port for use by AssertModeEnable

[Alon Levy]

This is called possibly before sleep, and otherwise during resolution
change and logout. To support the sleep case we need to flush all memory
on the device and render all surfaces, which is what the synchronous UPDATE_MEM
does.
