Subject: [PATCH RFC] ACPI: (x86) remove useless initial assignment in gsi_to_irq
Date: Mon, 31 Mar 2014 10:30:55 +0800 [thread overview]
Message-ID: <5338d375.45ac440a.2163.3105@mx.google.com> (raw)
From: Zhouyi Zhou <zhouzhouyi@gmail.com>
I think in function gsi_to_irq, initial assignment to irq is useless although compiler
may eliminate it during the compilng.
