Subject: [PATCH] Don't print an error message just because there's no i8042 chip

From: Peter Jones <pjones@...hat.com>

Some systems, such as EFI-based Apple systems, won't necessarily have an
i8042 to initialize.  We shouldn't be printing an error message in this
case, since not detecting the chip is the correct behavior.
