[PATCH] hwmon: Fix reboot on it87 driver load
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.
Plan the I2C interface for removal as well. If nobody complains within
a year, it will confirm my impression that the I2C interface isn't
actually needed by anyone.
