This is intended for use of a new driver. Of course a driver can
allocate its own buffer. But the purpose of the framework is to
make subdrivers easier to write. So if a larger buffer is needed
for some reason in the device's protocol, why not allocate it in the
framework?

Currently yes. Either the API must be extended or the driver
changed. As this is unlikely to remain the only driver with that
problem, I propose extending the API.
