From 1dcc3d3362b0c97e48290f7786be85b4cec2a147 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 17 Jul 2015 22:54:09 +0200 Subject: ACPI / bus: Move ACPI bus type registration Move the registration of the ACPI bus type to acpi_bus_init() and avoid using ACPI going forward if it fails (too many things depend on the presence of the ACPI bus type).
