Subject: [PATCH] drm/exynos: fix memory leak: free EDID block
Date: Tue, 20 Nov 2012 04:30:16 -0500 [thread overview]
Message-ID: <1353403816-8091-1-git-send-email-eich@suse.de> (raw)
In-Reply-To: <CAAQKjZPAUtsHWC7EvK=H2EQJY3zZhwnL6yKZmRMhsL3Wgi0UuA@mail.gmail.com>
drm_get_edid() returns a pointer to an EDID block. The caller
is responsible to free this pointer itself.
Here the pointer gets assigned to the local variable raw_edid.
Therefore it should be freed before the variable goes out of
scope.
