Marking the chip24 as read-only won't help recover from this. Also, if your chip25 has any software write-protect mechanism you may want to review the26 code to make sure this driver won't turn it on by accident.27 28 If you use this with an SMBus adapter instead of an I2C adapter,29 full functionality is not available.
