Subject: [PATCH] IOMMU-Tegra: gart: Delete an unnecessary check before the function call "vfree"
Date: Thu, 05 Feb 2015 18:00:25 +0100 [thread overview]
Message-ID: <54D3A1A9.9040709@users.sourceforge.net> (raw)
In-Reply-To: <5317A59D.4-Rn4VEauK+AKRv+LV9MX5uipxlwaOVQ5f@public.gmane.org>
From: Markus Elfring <elfring-Rn4VEauK+AKRv+LV9MX5uipxlwaOVQ5f@public.gmane.org>
Date: Thu, 5 Feb 2015 17:54:16 +0100
The vfree() function performs also input parameter validation.
Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
