If anyone has any objections, please let me know. ------------------ From: Rafael J. Wysocki [ 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.
