From 77ca04ccf0c9dc00104da8336024a6593b6305a6 Mon Sep 17 00:00:00 2001 From: Zhi Wang Date: Mon, 20 Jun 2016 08:17:02 -0400 Subject: [PATCH] drm/i915: Set the access right of kernel param "i915.enable_gvt" to read-only. The access right of kernel param "i915.enable_gvt" should be read-only as it only applies during module load (and is not *runtime* writable).
