Wysocki" Date: Mon, 17 Apr 2017 01:19:50 +0200 Subject: ACPI / scan: Apply default enumeration to devices with ACPI drivers From: Rafael J. Wysocki commit f5beabfe61794d9a9d9549d387cda2bffd81e504 upstream. The current code in acpi_bus_attach() is inconsistent with respect to device objects with ACPI drivers bound to them, as it allows ACPI drivers to bind to device objects with existing "physical" device companions, but it doesn't allow "physical" device objects to be created for ACPI device objects with ACPI drivers bound to them. Thus, in some cases, the outcome depends on the ordering of events which is confusing at best. For this reason, modify acpi_bus_attach() to call acpi_default_enumeration() for device objects with the pnp.type.platform_id flag set regardless of whether or not any ACPI drivers are bound to them.
