SubjectRe: [RFC PATCH] vmwgfx: Fix assignment in vmw_framebuffer_create_handle
Ryan,

Thanks for pointing this out. Unfortunately there seems to be two bugs
here, the one you pointed out and the fact that we set the handle to zero,
when it probably should be set to struct vmw_framebuffer::user_handle.

Jakob, can you comment on this?
