From 9da582984b632a75f562a304ff96dd1043281430 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Thu, 17 Oct 2024 09:57:41 +0200 Subject: [PATCH] udev: consider serial ports as unconfigured only if both port and iomem_base sysattr is zero Various archs do not know the "io port" concept, hence check for the "iomem" configuration, too.
