We have this code:
... sysram = vmalloc(size); if (!sysram) return -ENOMEM;
info = framebuffer_alloc(0, device); if (info == NULL) return -ENOMEM; ...
If the vmalloc() call succeeds but the framebuffer_alloc() call subsequently fails then we'll leak the memory allocated for 'sysram' with vmalloc().
