From 57b63d00df0ded2e3ac98a28588a87901704bad8 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Tue, 16 Feb 2016 13:18:12 +0200 Subject: [PATCH] drm/i915: drop write perm from module params which don't support changing We've given write permissions to dynamically change some module parameters through /sys/module/i915/parameters although they only support setting on module load. Fix the permissions.
