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

From: Armin Wolf
Date: Sun Apr 30 2023 - 16:32:29 EST


This patch series allows WMI drivers to retrieve the number of
WMI object instances. This functionality 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.

Changes since RFC v2:
- modify wmi_instance_count() to return an integer
