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.)
