platform/x86: intel-hid: Check ACPI_HANDLE() against NULL

2026-06-01T15:54:49+00:00

[ Upstream commit 5c69e090ae5dd93d910f70db0796357080707d26 ] 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-hid driver. Fixes: ecc83e52b28c ("intel-hid: new hid event driver for hotkeys") Signed-off-by: Rafael J.

platform/x86: intel-hid: Enable 5-button array on ThinkPad X1 Fold 16 Gen 1

2026-02-23T15:50:55+00:00

The Lenovo ThinkPad X1 Fold 16 Gen 1 has physical volume up/down buttons that are handled through the intel-hid 5-button array interface. The firmware does not advertise 5-button array support via HEBC, so the driver relies on a DMI allowlist to enable it. Add the ThinkPad X1 Fold 16 Gen 1 to the button_array_table so the volume buttons work out of the box.

platform/x86: intel-hid: Add Dell 16 Plus 2-in-1 to dmi_vgbs_allow_list

2026-02-23T14:31:03+00:00

The Dell 16 Plus 2-in-1 (model DB06250) requires the VGBS allow list entry to correctly enable the tablet mode switch. Without this, the chassis state is not reported, and the hinge rotation only emits unknown scancodes.

platform/x86/intel/hid: Stop creating a platform device

2025-12-16T20:51:04+00:00

Now that "system" devices are represented as platform devices, they are not claimed by the PNP ACPI scan handler any more and the Intel HID 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.

platform/x86/intel/hid: Add Dell Pro Rugged 10/12 tablet to VGBS DMI quirks

Dell Pro Rugged 10/12 tablets has a reliable VGBS method. If VGBS is not called on boot, the on-screen keyboard won't appear if the device is booted without a keyboard. Call VGBS on boot on thess devices to get the initial state of SW_TABLET_MODE in a reliable way.
