It looks to me like locking is only needed when we R/U/WB a register which has more than one "function", like is the case for fan clock dividers for the ADM1026. In the case a given register has only one function of interest to our driver, is there still a benefit in using the lock? Concrete example anyone? Thanks, -- Jean Delvare
