In this case buffer_info[] is a real flexible array, so there is not
much we can do.

The driver seems to only uses the structure to address memory. It is
not allocating the structure or doing any calculations based on its
size, so it should be fine (famous last words).

If anyone has access to the hardware it would be great if they tested it :)
