Subject: [PATCH 4/7] iommu/ipmmu-vmsa: Make IPMMU_CTX_MAX unsigned
Date: Wed, 20 Feb 2019 16:05:28 +0100 [thread overview]
Message-ID: <20190220150531.2462-5-geert+renesas@glider.be> (raw)
In-Reply-To: <20190220150531.2462-1-geert+renesas@glider.be>
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().
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
