[Xen-devel] [PATCH v2 3/5] drivers/video: Drop framebuffer size constraints



The limit 1900x1200 do not match real world devices (1900 looks like a
typo, should be 1920). But in practice the limits are arbitrary and do
not serve any real purpose. As discussed in "Increase framebuffer size
to todays standards" thread, drop them completely.

This fixes graphic console on device with 3840x2160 native resolution.
