Subject: [PATCH v1 3/5] ACPI: processor: perflib: Rearrange unregistration routine

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

Rearrange acpi_processor_unregister_performance() to follow a more
common error handling pattern and drop a redundant "return" statement
from the end of it.

No expected functional impact.
