Subject: [PATCH v2 0/5] platform/x86: Check ACPI_COMPANION() or ACPI_HANDLE() against NULL
Date: Tue, 12 May 2026 17:10:35 +0200	[thread overview]
Message-ID: <6007701.DvuYhMxLoT@rafael.j.wysocki> (raw)

Hi All,

This series replaces

https://lore.kernel.org/linux-acpi/4731840.LvFx2qVVIh@rafael.j.wysocki/

and as a whole it makes exactly the same code changes.

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 requisite ACPI_COMPANION() or ACPI_HANDLE() checks
against NULL to 5 platform/x86 drivers where they are missing.

Thanks!
