Would this be acceptable then?

ACPI: WMI: Improve Kconfig entry

From: Carlos Corbacho <carlos@strangeworlds.co.uk>

As Pavel Machek has pointed out, the Kconfig entry for WMI is pretty
non-descriptive.

Rewrite it so that it explains what ACPI-WMI is, and why anyone
would want to enable it.

Many thanks to Ray Lee for ideas on this.
