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().
