What are the consequences of the bug which you've fixed?

It helps very much if the changelog explains things like this so we can
decide whether the patch is needed in 2.6.25 or even 2.6.24.x.

Thanks.

There is no direct negative impact; this is mostly cleanup that unifies
sysfs representation of ACPI input devices. The patch was submitted for
2.6.24-rc at the same time as similar patches for other ACPI input devices
but was lost for whatever reason.

I guess it can safely wait for post-2.6.25.
