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")
