It looks like a pretty useless message to me, AFAICT. If it is only an
APM hint, then we probably shouldn't say anything in dmesg but simply
ignore it.

I mean, do I additionally want to know that I just connected to AC after
I just plugged the cable in? There's this green lamp on the side, doh!
:-)

Thanks.

I guess we can drop that pr_info, and please block the issuing of the
event to userspace, like this:

case TP_HKEY_EV_AC_CHANGED:
/* X120e, x121e, X220, X220i, X220t, X230, T420, T420s, W520:
 * AC status changed; can be triggered by plugging or
 * unplugging AC adapter, docking or undocking, or closing
 * or opening the lid. */

/* fallthrough */

and letting it proceed to the TP_HKEY_EV_KEY_NUMLOCK block.

Also, do we have any confirmed reports about the lid switch
causing event 0x6040?  It doesn't look right... the comment
might need to be updated.

I could not reproduce it on my X220. Would you prefer even stronger wording
or should I get of it entirely?

If you cannot reproduce it, we can shalk it up to user error or to corrected
firmware bug, so you can remove any mention of lid open/close to event
6040...

OK, great.

After some more testing, I suspect he closed the lid and then
(un)plugged/docked.

Thanks for the two ACKs.

Just to make sure: From how I read the (outdated) Copyright section, you
are the maintainer of thinkpad_acpi and thus will copy over the ACKs into
my commit message, merge, and forward into what will become 3.9 at some
point, correct?

Usually the subsystem maintainer picks such simple patches and ACKs directly
from the platform-driver-x86 list email, adds his signed-of-by, and
eventually sends it to Linus.

For this "obviously correct" single-code-line fix, we might even lucky
out and it could make it to 3.8, depends on his judgment.

Just so this does not get lost, neither Linus' tree nor [1] carry this
patch, yet. Is there anything more I can/should do?

Sadly, no.
