Subject: [PATCH] ACPI: processor: idle: Drop unnecessary statements and parens

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

Drop a redundant "else", a "return" statement at the end of a void
function and redundant parentheses around an unsigent int variable
name from the ACPI processor idle driver.

No expected functional impact.
