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.
Bugzilla: N/A
Upstream-status: Fedora mustard
