Hello,
Upon switching on my thinkpad T460 running Arch Linux with the "linux-
mainline" kernel : 4.6.0-rc2-mainline
I recieve the following error message from thinkpad_acpi:
Apr 11 17:00:44 archibald kernel: thinkpad_acpi: ThinkPad ACPI Extras

Apr 11 17:00:44 archibald kernel: input: ThinkPad Extra Buttons as
/devices/platform/thinkpad_acpi/input/input7
I believe this bug has been reported, but I also thought that a patch
had been submitted and the bug was fixed in recent versions of the
kernel?
I also have this problem when booting form the standard Arch kernel
(4.4).
Regards,
Doug
