You are right! The code should check the revision and allow read-after-write for rev2 only. Or better, return error on rev1; we can expect any further revision will implement it correctly. Definitevy the revision can be retrieved by SW and used for the check. Today rev# is already retrieved during probe() and printed. Should be enough to keep it in a new field of the private date struct. Thanks for the hint.
