Subject: [PATCH v2 3/6] iommu/ipmmu-vmsa: Make IPMMU_CTX_MAX unsigned
Date: Wed, 3 Apr 2019 20:21:45 +0200 [thread overview]
Message-ID: <20190403182148.18058-4-geert+renesas@glider.be> (raw)
In-Reply-To: <20190403182148.18058-1-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().
