Subject: [PATCH 06/30] ACPI-processor: Move a success indication in
 acpi_processor_preregister_performance()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 6 Sep 2016 13:03:56 +0200

The local variable "retval" was initialised with a zero at the beginning
as an indication for a successful function execution despite of
the possibility that following function calls could fail.
Move the desired assignment down to the source code place where some system
clean-up is performed.
