+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

+Some devices (like the nuforce udac) spew this quite a lot.
+This patch kinda sucks, but it'll shut things up for now.
+
+Probably not an upstream candidate. I suspect the answer would be
+"don't turn SND_DEBUG then"
