Subject: [PATCH 4/7] iommu/ipmmu-vmsa: Make IPMMU_CTX_MAX unsigned
Date:   Wed, 20 Feb 2019 16:05:28 +0100
Message-Id: <20190220150531.2462-5-geert+renesas@glider.be>
In-Reply-To: <20190220150531.2462-1-geert+renesas@glider.be>
References: <20190220150531.2462-1-geert+renesas@glider.be>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Make the IPMMU_CTX_MAX constant unsigned, to match the type of
ipmmu_features.number_of_contexts.

This allows to use plain min() instead of type-casting min_t().
