Bugzilla: N/A
Upstream-status: Fedora mustard
From b4e96f34c17e5a79cd28774cc722bb33e7e02c6e Mon Sep 17 00:00:00 2001
From: Peter Jones <pjones@redhat.com>

Subject: [PATCH] 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.

Socket fuzzers like sfuzz will trigger this printk a lot, even though it's
ratelimited. It isn't particularly useful, so just remove it.

This was removed in revision 1.6 of linux-2.6-silence-noise.patch
in ye olde CVS tree. I have no idea why. Originally the pr_debug in
device_pm_remove was nuked as well, but that seems to have gotten lost in
the r1.634 of kernel.spec (2.6.26-rc2-git5.)
