From: Peter Jones Date: Thu, 25 Sep 2008 16:23:33 -0400 Subject: [PATCH] input: silence i8042 noise Don't print an error message just because there's no i8042 chip. 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.
