| |
-stable review patch. If anyone has any objections, please let us know. ------------------
Only scan I2C address 0x2d. This is the default address and no IT87xxF chip was ever seen on I2C at a different address. These chips are better accessed through their ISA interface anyway.
This fixes bug #5889, although it doesn't address the whole class of problems. We'd need the ability to blacklist arbitrary I2C addresses on systems known to contain I2C devices which behave badly when probed.
