Subject: [PATCH] drm/i915: Don't leak VBT mode data
Date: Mon, 14 Sep 2015 19:24:18 -0700	[thread overview]
Message-ID: <1442283858-27254-1-git-send-email-matthew.d.roper@intel.com> (raw)

We allocate memory for LVDS modes while parsing the VBT at startup, but
never free this memory when the driver is unloaded, causing a small
leak.
