Hash : c0414119
Message : * src/cff/*: Clean up interface. Ensure that all driver functions use the signature of the service or driver. This avoids pointer mismatches, which are technically undefined behaviour. Recent compilers are more picky in catching them as part of Control Flow Integrity tests.
