+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
