From 8466169ab9fe9f0c3412881116aca895feea6e70 Mon Sep 17 00:00:00 2001 From: Michel Thierry Date: Mon, 8 Jan 2018 10:37:34 -0800 Subject: drm/i915/gvt: Do not use I915_NUM_ENGINES to iterate over the mocs regs array The mocs reg array is defined locally but then we iterate over its elements using I915_NUM_ENGINES. There is no 'hard' connection between I915_NUM_ENGINES and the regs array and there will be problems if either of them increases. Use the size of the mocs reg array instead to safely iterate over it.
