Subject: [PATCH 4/5] drm/i915: clear opregon->lid_state after we unmap it
Date: Thu, 12 Sep 2013 13:58:20 -0300 [thread overview]
Message-ID: <1379005101-1500-4-git-send-email-przanoni@gmail.com> (raw)
In-Reply-To: <1379005101-1500-1-git-send-email-przanoni@gmail.com>
From: Paulo Zanoni <paulo.r.zanoni@intel.com>
We don't seem to be using the pointer after it's unmapped, so this
patch doesn't fix any bug I can reproduce.
