From bbaa5c41fad29e9f6b4f1975103d530dc1391772 Mon Sep 17 00:00:00 2001 From: Bernhard Beschow Date: Fri, 28 Oct 2022 12:34:18 +0200 Subject: [PATCH] hw/i386/acpi-build: Resolve redundant attribute MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The is_piix4 attribute is set once in one location and read once in another. Doing both in one location allows for removing the attribute altogether.
