This patchset proposes a new option for risky i2c addresses between 0x78 and 0x7f that are currently disabled. This behavior is marked as not recommended, but is sometimes needed if you have a device using an address in this range. It was inspired by an email from Wolfram Sang [1] that encouraged to add this option for using i2c-tools with devices using this address range.
