From 1d7ea915003a2064dc542ffee8d02104a2dee728 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Wed, 8 Jun 2022 09:53:29 -0400 Subject: [PATCH] acpi: applesmc: use AcpiDevAmlIfClass:build_dev_aml to provide device's AML .. and clean up not longer needed conditionals in DSTD build code. applesmc AML will be fetched and included when ISA bridge will build its own AML code (incl. attached devices). Expected AML change: the device under separate _SB.PCI0.ISA scope is moved directly under Device(ISA) node.
