When there's a conflict, it outputs a warning message with all the details needed to properly diagnose the underlying issue. However, the i2c-nforce2 driver also prints its own message. Not only is the message redundant, it is at the KERN_ERR level, which overrides some bootsplash screens for no good reason. This change removes the two lines that print out the error messages.
