From 922952f2bbcfe21375973d0ea0e662a1a4837b10 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 12 May 2026 16:11:43 +0200 Subject: [PATCH] platform/x86: intel/smartconnect: Check ACPI_HANDLE() against NULL MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Every platform driver can be forced to match a device that doesn't match its list of device IDs because of device_match_driver_override(), so platform drivers that rely on the existence of a device's ACPI companion object need to verify its presence. Accordingly, add a requisite ACPI_HANDLE() check against NULL to the platform/x86 intel/smartconnect driver.
