The driver will retry a given number of times +and cause read errors. Or maybe the W83L785TS-S chip is simply unreliable, +we don't really know. The driver will retry a given number of times (5 by default) and then give up, returning the old value (or 0 if there is no old value). It seems to work well enough so that you should not notice anything.
