Not sure I understand the concern since this is a constant which will always be "2". But if you must cast, do it in snprintf() and not in the macro definition. checkpatch also complains about the cast. I would prefer for all instances of this to be consistent, though. So whatever you do, please also fix qla4xxx. -- Martin K. Petersen Oracle Linux Engineering
