From 9001c07995fdd1f3657408c71bca7d6c5fb87fd3 Mon Sep 17 00:00:00 2001 From: Heikki Krogerus Date: Wed, 18 Mar 2015 12:55:12 +0200 Subject: [PATCH] serial: 8250_dw: remove useless ACPI ID check Having ACPI handle does not mean the same as having ACPI identifier. The check is in any case useless, but having it prevents this driver from being used for example with multifunctional PCI devices, such as the newer Intel LPSS devices.
