From 686e905aeea524b957a8584c8c1e5060111ad4da Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 15 Dec 2025 14:35:44 +0100 Subject: [PATCH] platform/x86/intel/vbtn: Stop creating a platform device Now that "system" devices are represented as platform devices, they are not claimed by the PNP ACPI scan handler any more and the Intel virtual button array platform devices should be created by the ACPI core, so the driver does not need to attempt to create a platform device by itself. Accordingly, make it stop doing so. No intentional functional impact. Signed-off-by: Rafael J.
