[PATCH 0/2] HID: steelseries: Add Rival 3 Wireless battery reporting

[Martin Oberleiter via B4 Relay]

The SteelSeries Rival 3 Wireless mouse reports its battery level on
request through its 2.4 GHz receiver, using the protocol rivalcfg
implements. This series exposes it as a power supply.

Patch 1 makes HID_STEELSERIES select POWER_SUPPLY, which the Arctis
headset support already needs and which patch 2 relies on as well.

Patch 2 adds the battery reporting. Desktops currently show the mouse's
battery with a keyboard icon: upower picks the kind from the sibling
input devices and prefers the mouse's auxiliary keyboard interface. That
is a upower heuristic and will be reported there separately.

Tested on a Rival 3 Wireless (receiver 1038:1830) over a night with the
mouse switched off and on again.

The series was written with the help of an AI coding assistant (Claude
Code); details are in the changelog of patch 2.
