Subject: [RFC v2 0/2] platform/x86: Allow retrieving the number of WMI object instances

This experimental patch series allows WMI drivers to retrieve
the number of WMI object instances. This functionallity benefits
several current and upcoming WMI drivers, the dell-wmi-sysman driver
is converted to use this new API as an example.

The changes are compile-tested only, the change to the dell-wmi-sysman
driver also needs to be tested on real hardware.

  platform/x86: dell-sysman: Improve instance detection
