[PATCH] i2c: Fix union i2c_smbus_data definition
The i2c_smbus_data union block member has a comment stating that an extra byte is required for SMBus Block Process Call transactions. This has been true for three weeks around June 2002, but no more since, so it is about time that we drop this comment and fix the definition.
