Subject: [PATCH] platform/surface: aggregator_registry: omit battery & AC nodes on Surface Laptop 7
Date: Thu,  9 Apr 2026 15:43:47 +1200	[thread overview]
Message-ID: <20260409034347.17381-1-oliverjwhite07@gmail.com> (raw)

Surface Laptop 7 exposes battery and AC status via Qualcomm PMIC GLINK
qcom_battmgr. Registering the standard SSAM battery and AC client
devices on this platform causes duplicate power-supply devices to
appear.

Drop the SSAM battery and AC nodes from the Surface Laptop 7 registry
group so that only the qcom_battmgr power supplies are instantiated.

Fixes: b27622f13172 ("platform/surface: Add OF support")
