I think there's a risk of user confusion here, in that it's now possible for the mic mute light to be lit despite the internal microphone still being active. That seems like surprising behaviour.

That seems like surprising behaviour. Yeah, that is a legitimate concern. Patches 1/3 [1] and 2/3 [2] clearly make sense, as they're generic and don't really suggest any new behavior. But setting this behavior here as the default could indeed be a bit unexpected. I think it's fair to reject this patch (3/3), but accept the first two. Tweakers who have the same early boot caps-lock LED needs as me can simply put this in their initramfs after 1/3 and 2/3 are applied: # echo caps-lock > /sys/devices/platform/thinkpad_acpi/leds/tpacpi\:\:micmute/trigger Jason [1] https://lkml.org/lkml/2013/8/22/310 [2] https://lkml.org/lkml/2013/8/22/313 -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

It is a LED misuse, and it will get in the way when we finally put that LED to its proper use.

Thinkpads with a micmute LED do not have a capslock LED. The micmute LED is currently not used by any piece of Linux kernel land or user land. It seems reasonable to hook it up to caps lock, at least by default, so users can have some degree of functionality. Signed-off-by: Jason A.
