Marking the chip 185195e509SWolfram Sang as read-only won't help recover from this. Also, if your chip 195195e509SWolfram Sang has any software write-protect mechanism you may want to review the 205195e509SWolfram Sang code to make sure this driver won't turn it on by accident. 215195e509SWolfram Sang 225195e509SWolfram Sang If you use this with an SMBus adapter instead of an I2C adapter, 235195e509SWolfram Sang full functionality is not available.
