[PATCH v1 3/5] ACPI: scan: Drop sta argument from acpi_add_single_object()

From: Rafael J. Wysocki
Date: Wed Apr 07 2021 - 10:34:14 EST


From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

Move the initial status check for ACPI_BUS_TYPE_PROCESSOR objects
into acpi_add_single_object() so it is not necessary to pass the
"sta" argument to it, get rid of that argument from there and update
the callers of that function accordingly.

No intentional functional impact.
