X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=77ca04ccf0c9dc00104da8336024a6593b6305a6;p=linux-beck.git 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).
