From 2c7f9a4df9def07867087a520bc32169e2eec9f8 Mon Sep 17 00:00:00 2001 From: Colin Xu Date: Thu, 14 Feb 2019 12:56:33 +0800 Subject: [PATCH] drm/i915/gvt: Use consist max display pipe numbers as i915 definition GVT implements a homogeneous vGPU as host GPU so max vGPU display pipes can't exceed HW. The inconsistency definition has potential risks which could cause array indexing overflow. Remove the unnecessary define of INTEL_GVT_MAX_PIPE and align with i915.
